Title: Exoplanetary Atmospheres in 3D: implications from radiation-chemistry
       (cloud)-hydrodynamics simulations
Speaker: Nathan Mayne, University of Exeter

Abstract: In this presentation I will detail some of our efforts to apply 3D
climate models to the study of exoplanets. Firstly, I will give a brief overview
of the observations and the key questions they pose, before detailing the
approach we have adopted at the Exeter Exoplanet Theory Group. Our studies are
based on the UK Met Office 3D model, termed the Unified Model, and I will
briefly describe the development environment before presenting some of the
physical applications. Starting with gas giant planets, and particularly hot
Jupiters, I will show how the atmospheric flows act to move the large scale
structure, chemical state and observations away from that predicted through
equilibrium and/or 1D considerations. Time permitting, I will very briefly show
results from state-of-the-art 3D simulations of gas giants including clouds,
before finishing with applications to terrestrial exoplanets, exploring the
importance of convection, and how it is treated, in setting the overall climate
of tidally-locked planets.

Pulsar Timing Arrays – Group Study/Journal Club

Friday 7 May 2021, 1400 Hours
Via Zoom: https://bham-ac-uk.zoom.us/j/87042723078?pwd=TkVYcFZJeHlzTUlGai9YOEZhTUI3Zz09

A small group of us have decided to run something between a group study and
journal club this term to improve our knowledge of pulsar timing arrays.

The next few years are expected to be a golden age for pulsar timing array
(PTA) science. The recent tentative claim of a detection of an astrophysical
signal in the NANOGrav 12.5-year data set is expected to be confirmed, thereby
opening a new observational window on supermassive black holes.

Everyone in the group is welcome to attend. Please circulate this link to
anyone you think might be interested. We will meet once a week, on Fridays
at 2.00pm, starting next week (7th May). We expect this to run for between
6-8 weeks.

Speaker: Abbas Askar, Lund University
Title: The formation of gravitational wave sources in star clusters:
       From stellar to intermediate-mass black holes

Abstract:
Over the past five years, several merging compact object binary systems have
been detected through gravitational waves by the LIGO /Virgo detectors. While
these observations provide a new window to observe the universe, they also
raise important questions about the astrophysical origin and formation of
these elusive binary systems. In this talk, I will discuss the various
processes by which gravitational wave sources can form in dense stellar
clusters. The retention and long-term evolution of compact objects in stellar
clusters depends on a variety of physical processes that are not fully
understood. I will give an overview of these processes and explain how they
shape the properties and merger rates of binary black holes that originate in
dense environments. Additionally, it has also been suggested that massive and
dense star clusters could be potential sites for forming black holes with
masses between ~ 100 to 10,000 solar masses. I will talk about the key
processes and caveats involved in the formation, retention and growth of
these intermediate-mass black holes in the densest star clusters. I will also
discuss how these clusters that host intermediate-mass black holes can end up
in the galactic centre where they may play a role in seeding the formation of
super-massive black holes.

Wednesday 28 October 2020, 1600 via zoom
Speaker: Jan Zalasiewicz, University of Leicester
Title: The New World of the Anthropocene

Abstract:
Human civilization has grown around the stable shorelines and climate, and
amid the diverse biosphere of, the last ten millenia or so of the Holocene
Epoch: the latest of many interglacial phases of the Quaternary Ice Age, and
the one that the created the world we live in. The growth of human civilization
has now put that stability into question. With the explosion in both human
numbers and energy use since the Industrial Revolution has come sharp and
large-scale changes to landscape, biosphere and climate. These rapid and
large-scale changes have led to the suggestion that we are now living through
the beginning of the Anthropocene Epoch – an interval of geological time
dominated by human influence. The term was proposed just two decades ago by
Paul Crutzen, the Nobel Prize-winning atmospheric chemist, and has since been
widely used – and sharply debated. Its analysis needs converting the various
kinds of environmental change into different kinds of geology. Physical change
is most strikingly represented by the spread of the ‘urban stratum’, the
refashioning of sand, clay and limestone into our buildings, foundations and
transport systems. Biological changes include the ongoing mass extinction event
and the effect of invasive species (while human-made ‘anthroturbation’ is as
extraordinary as anything in the fossil record). Chemical changes include the
reshaping of the Earth’s natural carbon, phosphorus and nitrogen cycles. The
combined change is of a scale to leave a signal, in strata now forming, that
will persist for many millions of years. Of more immediate significance is
how this new concept in Earth history might be used to help us navigate the
conditions of a changing planet over the decades and centuries to come.

In place of our normal in-person Astronomy in the City events, we are starting
a series of virtual events which are designed to bring you all the familiar
highlights. We hope you will be able to join us for the first event on
Wednesday, 28 October 2020 at 18:00. It will feature talks live streamed via
YouTube followed by a live Q&A session on the Zoom platform.

The links to the talks and Q&A can be found at the Astronomy in the City
webpage: http://www.sr.bham.ac.uk/observatory/astronomyinthecity.php

In this first event, we will feature a talk by University of Birmingham PhD
student Andris Dorozsmai called “The great debate in astronomy - the
Shapley/Curtis debate on the scale of the Universe” as well as a talk about
the night sky in November. Following this, you will have the chance to ask
assembled experts any astronomical questions you may have.

We are currently planning a second event for 25 November 2020, with more
expected in the New Year. We hope to welcome you to one of these virtual
events. Dr Sean McGee, University of Birmingham Observatory Director on

Title: Insights on stellar rotation and magnetism from main-sequence solar
       like stars to red giants

Abstract:
During the last 15 years, photometric data of large samples of stars have been
collected thanks to space missions such as CoRoT, Kepler/K2 or TESS . The high
quality of these data have allowed us to progress on different fields of
astrophysics from exoplanet search to stellar physics, including
galactic-archeology. The study of standing waves generated in stars proved that
they carry crucial information to probe stellar interiors. The asteroseismic
analysis of the the aforementioned data opened a window on the interior of
solar-like stars with an external convective envelope. For instance, it is
possible to measure the depth of these convective envelopes in main-sequence
solar-like stars or to determine the rotation rate of the core of subgiants
and red giants, showing that those rates are much slower than what is predicted
by standard solar models.

Understanding the transport of angular momentum is crucial to better determine
the stellar ages when using stellar evolution models. More than 40 years ago,
Skumanich (1972) showed how rotation and magnetic activity decreased with the
age of a solar-like star. While this result was based on the study of young
cluster stars, later observations of other clusters, still younger than the
Sun, agreed with this age-rotation or “gyrochronology” relationship. With more
recent studies based on Kepler data, this empirical relation does not seem to
hold, opening new questions on stellar dynamics evolution.

In this talk, I will focus on targets from solar-like stars to red giants where
rotation and magnetism could be measured with photometric data. I will show
how the photometric data of Kepler is providing key information on the
understanding of angular momentum transport in stars and of magnetic activity
at different evolutionary stages of a star like the Sun.

Physics Colloquium

Wednesday 14 October 2020, 16.00 via zoom
Speaker: Gerald Gabrielse, Northwestern/Harvard
Title: Tabletop Tests of the Standard Model and Beyond: A Tale of Two
       Electron Dipole Moments.

Abstract:
The standard model of particle physics—a set of particles, interactions and
symmetries knitted together by field theory—is the great triumph and the great
frustration of modern physics. The great triumph is its ability to predict the
outcome of laboratory tests with exquisite precision. The great frustration is
its inability to account for basic features of the universe, like how it
survives annihilation after the big bang, why it is made of matter rather than
antimatter, why does gravity not fit well, what is dark matter, etc. The
magnetic and electric dipole moments of the electron, measured using completely
differently methods, illustrate the crucial role of tabletop measurements for
testing the standard model and beyond.

The electron’s magnetic moment, determined to 3 parts in 10^{13}, is the most
precisely determined property of an elementary particle. The measurement with
a one-electron quantum cyclotron tests the most precise prediction of the
standard model. A ten times more precise measurement is currently being
pursued in light of an intriguing 2.4 standard deviation discrepancy that has
recently emerged between the measurement and the prediction. A positron
measurement at the new precision should provide a 200 times improved test of
the standard model’s fundamental CPT symmetry invariance with leptons.

The electron electric dipole, measured using the incredibly strong internal
field on valence electrons within cold molecules in a cold beam, is an
extremely sensitive probe for physics beyond the standard model. The standard
model requires 4th order perturbation theory to produce the CP violation needed
for an electric dipole, while supersymmetric models and other proposed
beyond-the-standard-model improvements predict much large electric dipoles
moments from first order perturbation theory. Following two previous
order-of-magnitude improvements in sensitivity, a new measurement seeks to
improve the sensitivity by another order of magnitude.

Title: Integrability of eccentric, spinning black-hole binaries up to second
       post-Newtonian order

Abstract:

Accurate gravitational waveforms are necessary for LIGO and LISA sources, and
especially for the prospect of multi-band gravitational wave observations.
Computing these waveforms accurately is expensive because of the complicated
precession dynamics over a very large number of orbits.  The most complicated
scenario is an eccentric binary where both spins and the orbital plane are
precessing.  Current state-of-the-art waveform models rely on analytical
approximations like orbit averaging and a small-eccentricity expansion.  I
will present work towards avoiding these approximations by exploiting
integrability of the Hamiltonian dynamics of eccentric, spinning black hole
binaries.  Integrability lets us construct action-angle variables, which make
the evolution very simple for arbitrarily long times.  We will present four
out of five of the action integrals at 1.5PN.  And while post-Newtonian
corrections break integrability, we can recover it in a perturbative sense.
We will present explicit (perturbative) constants of motion at 2PN order, and
the method that was used to find them.

Cheers Silvia

Abstract:
In addition to being the sources of exotic supernovae and gravitational waves,
binary stars allow for interesting new insights in stellar astrophysics. The
pulsations of tidally distorted stars in close binaries are "tidally trapped,"
exhibiting amplitude modulated over the orbital period. I will demonstrate why
this tidal trapping occurs and will discuss how tidally trapped pulsations may
be used for asteroseismology. Stellar oscillations are also excited by tidal
forcing, leading to tidal synchronization and circularization. I will show
compelling observational evidence that a resonance locking process operates
in both planetary systems and stellar binaries such as heartbeat stars, driving
synchronization that can be much more efficient than prior expectations.
Finally, I will examine new discoveries of binary white dwarfs with sub-hour
orbital periods, discussing implications for their formation, tidal physics,
gravitational wave signals, and their impending demise.

Title: The statistical era of strong gravitational lensing cosmology

Abstract: Local measurements of the expansion rate are in tension with those
inferred from observations of the distant Universe. Is this the first sign of
new physics or merely a sign of systematic errors within individual probes?
This key question remains unsolved, because there are only a handful of
established probes. Here I will talk about how strong gravitational lensing
offers a new window on precision cosmology, shining a new light on the dark
Universe. I will present strong lensing constraints on the expansion rate of
the Universe and the equation of state of dark energy. I will also show how
lensing combined with stellar dynamics yields the most precise test to date of
the validity of General Relativity on extragalactic scales.

Physics Colloquium

Title: From Galaxy Zoo to LSST, Citizen Science in the age of Big Data.

Abstract: Citizen Science projects such as Galaxy Zoo (launched in 2007) have
demonstrated that hundreds of thousands of volunteers can make significant
contributions to astronomical research. Project Principal Investigator Chris
Lintott will review the latest results from the project, covering both 
orphological studies of large populations of galaxies and unusual objects such
as ‘Hanny’s Voorwerp’, a galaxy-scale light echo.  Galaxy Zoo inspired the
creation of the Zooniverse platform, which now hosts nearly 100 projects -
using recent astrophysical examples, including searches for supernovae and
strong lenses, Lintott will argue that there will be a place for volunteer
classification well into the next decade, highlighting in particular novel
machine learning approaches which manage the division of effort between
volunteers and machines in a flexible, optimised manner. The talk includes at
least one picture of penguins.

The colloquium with be followed-up with light refreshments accompanied byr

Title: New Physics from Old: Medieval Science and the Ordered Universe Project.

Abstract: For the English polymath, Robert Grosseteste, light was the
fundamental first form that gave dimensionality and stability to the material
world. In a dozen scientific treatises written in the early 13th Century, he
postulated an early physics of light, colour and the rainbow. In his De luce
(on light) he extends it to the origin of the Universe in what has been
referred to as the ‘Medieval Big Bang’. His arguments are so taut that they
can be translated into mathematics – our resulting numerical simulations show
that Grosseteste’s model does actually work. He also described the method for
developing a universal principle from repeated observations under controlled
conditions and argued that the explanation needing fewer suppositions and
premises was the best. In his theory of colour, we have found through close
examination of the manuscript evidence for his De colore (on colour) and his
De iride (on the rainbow) and a mathematical analysis of their content, that
he presents the first three-dimensional theory of perceptual colour space.

In this talk, I introduce Robert Grossteste (ca 1170 -1253), the scientist,r
 teacher, theologian and bishop and describe how a unique collaborative
research approach has revealed new insights into his thought, particularly on
light. An interdisciplinary team of historians, scientists, linguists and
philosophers has developed techniques of joint reading of the medieval texts
that have shown them to be logically consistent and founded on mathematically
based models. We reflect on how a study of this extraordinary medieval
science can help throw fresh light on the history of scientific thought, and
bridge the current perception gap between the study of science and humanities.
The greatest surprise of all is that the project has stimulated many new pieces
of science of contemporary interest (whose publications contain some unusually
old references...)

Title: Rage against the dying of the light: Type la supernovae at 1000 days
and beyond

Abstract: Type Ia supernovae (SNe Ia) have famously been used as standard
candles, a use that led to the discovery that the expansion of the Universe
was accelerating under the influence of a mysterious new phenomenon called
"dark energy." And yet, we still do not have a clear picture of the progenitors
of SNe Ia, i.e., what types of star systems end up exploding as these
supernovae. For obvious reasons, most observers study these supernovae when
they are young and at their brightest. In my talk, I will present recent
results from studies of SN Ia rates, from non-detections of SNe Ia in
different types of observations, and from SN Ia observations taken thousands
of days after explosion. I will specifically emphasize how Hubble Space
Telescope observations of old SNe Ia >1000 days after explosion reveal new
information on the progenitors and physics of the explosions and their
aftermath.

Astronomy in the City

Wednesday 29 January 2020, 6:15 pm, Poynting Building Large Lecture Theatre S02

University of Birmingham Lecturer Dr Davide Gerosa will discuss his work
in a talk titled: "Somewhere in between astronomy and relativity". He will
discuss how, until recently, everything we know about the Universe (planets,
stars, galaxies...) came to us through light. Straddling the boundaries between
astronomy and relativity, gravitational waves provide a fundamentally new way
of exploring the cosmos. Why would we only look at the Universe when we can
also hear it?

Astronomy in the City is a series of free all-ticket public events, each
packed with astrophysics; stargazing, and tea and biscuits. Evenings begin
with talks covering astronomical highlights and recent research, and a
question-and-answer session (for everything from beginner's questions about
the night sky to the latest work done here in Birmingham). Afterwards, (if
the weather cooperates) we have observing with telescopes on campus.

Tickets are available from https://astrointhecity290120.eventbrite.co.uk

This will be the third Astronomy in the City event of the 2019/2020 season.
A final event of the season is 4 March 2020. More details are on our website:

Title: Double Neutron Stars with LISA: What low-frequency gravitational waves
       tell us about binary star evolution?

Abstract:
The Advanced LIGO and Advanced Virgo detectors are producing several tens of
(and growing) highly significant and credible gravitational wave candidates.
The exploration of double compact object population statistics is integral to
constraining the relative importance of different formation channels and
reducing the large uncertainties that characterise key stages of isolated
binary evolution. I discuss how binary evolution physics may be imprinted in
low-frequency gravitational waves of inspiralling double neutron stars (DNSs).
In particular, I talk about some of the recent predictions of detection rates
and properties of DNSs expected to be observed by future spaceborne
interferometer LISA.

Speaker: Prof Sera Markoff, University of Amsterdam
Title: Imaging (and imagining) Black Holes

Black holes are one of the most exotic consequences of General Relativity, yet
they are also very common players in the Universe, existing on scales ranging
from the stellar up to beasts over a billion times more massive than our sun.
Contrary to their reputation as cosmic vacuum cleaners, they actually power
some very energetic processes that can even influence the growth of galaxies.
Furthermore, when black holes launch enormous jets of relativistic plasma,
they can accelerate particles to energies millions of times higher than
the Large Hadron Collider at CERN .

Astronomers, astrophysicists and physicists all have reasons for wanting to
understand black holes, yet we have been limited by the resolution of our
telescopes from actually seeing one directly. This situation has changed
dramatically with the coming of the Event Horizon Telescope (EHT),
an Earth-sized array operating in the millimeter wavelength regime that can
resolve the event horizons of two nearby supermassive black holes: the black
hole in the active galactic nucleus M87 (published this past April) and
Sgr A* in our own Galactic centre.

I will put these recent results into context by explaining a bit more about
the development of this project, as well as accretion onto black holes, and
methods for modelling and interpretation. I will also present some of the
areas where we still have major questions, and give some examples of the
current cutting edge in modelling and interpretation, as well as challenges
for the coming years that relate to black holes of all sizes,
including stellar-mass.

Title: Towards realistic simulations of dense stellar systems and the
       formation of gravitational wave sources

Abstract:
Dense stellar systems are the formation sites of stellar binaries and triples,
which can eventually evolve to become gravitational wave (GW) sources.
Modelling this process is crucial for uncovering formation channels
and estimating detection rates of gravitational wave events from stellar mass
objects. Simulating dense stellar systems is challenging due to the
multi-physics aspect of the problem. Realistic models should combine
gravitational N-body dynamics, Post-Newtonian effects, stellar evolution,
rotational spins, tidal dissipation etc. The outcome of such detailed
simulations provide not only the astrophysical history of GW sources, but
also the initial conditions for fully relativistic simulations of the actual
merger.

I will present an overview of my research projects in which I gradually
increase the complexity of my simulations, ranging from black hole formation,
star-gas interactions and dissolution of triple systems.

Tjarda will be in Birmingham from Monday to Thursday. You can find him in

Speaker: Hanno Rein, University of Toronto
Title: Long-term dynamical simulations of planetary systems

Abstract:
Accurately predicting the motion of planets has kept astronomers busy since
antiquity. After Newton published his law of universal gravitation in 1687,
it became clear that none of the planets’ orbits were perfectly periodic.
This immediately leads to the question of whether the Solar System can remain
stable over long timescales. By the end of the 18th century Lagrange and
Laplace were able to formulate an analytic theory which was in good agreement
of observation, but the question of stability remained unanswered until
a few decades ago.

Only the advent of fast computers made it possible to calculate the motion of
planets accurately enough to find that the Solar System is on the brink of
instability and has a finite chance of going unstable within the lifetime of
the Sun.  Although we have solved the question about the Solar System’s
stability, the discovery of thousands of other planetary systems beyond our
own Solar System presents new challenges for fast and reliable numerical
integration methods. We need these tools to validate and characterise
planetary systems as well as to understand their formation history. After a
historical overview of the subject at the beginning of my talk, I will discuss
why this is such a hard problem from a mathematical point of view, and how one
can nevertheless solve it. I will present some recent developments of
numerical integrators with very high accuracy.

Title: Fabrication of Ta2O5, Zr:Ta2O5 and aSi by ECR ion beam deposition for
use as high-index coating layers in ultra-stable optical cavities with low
Brownian thermal noise

Abstract: Precision metrology applications, such as mHz-linewidth laser
cavities for optical clocks and stabilized frequency combs, and fundamental
physics experiments such as gravitational wave detectors, impose stringent
requirements on optical and mechanical losses in the multilayer HR mirror
coatings. In the case of current and future gravitational wave detectors, only
ion beam deposition (IBD) has been demonstrated to satisfy the optical
requirements over suitably large areas (mirror diameter ≥340 mm). Advanced
gravitational wave detectors currently use mirror coatings fabricated from
multilayers of silica (SiO₂, low index) and alloys of tantalum pentoxide and
titanium dioxide (Ti:Ta₂ O₅, high index). Coating Brownian thermal noise,
which predominantly arises from the high index materials, sets an important
limit on the astrophysical reach of all current and future detectors.
Developing materials and methods by which the thermal noise can be reduced by
a factor of 2, whilst maintaining the required optical properties, is a goal
for the various international projects in this field.

This presentation will provide an overview of the first use of electron
cyclotron resonance (ECR) IBD processes for the fabrication of optical thin
film coatings, with unprecedented levels of optical and mechanical
losses. ECR ion sources provide a number of key benefits compared to standard
RF ion sources, through extending the accessible ion energies by an order of
magnitude, and in the removal of grids (contamination) in the plasma extraction
process. Amorphous silicon fabricated by ECR-IBD has been demonstrated to have
optical absorptions down to k = 1.2 × 10⁻⁵ at 1550 nm, the lowest ever
reported, and with potential to reach the thermal noise requirements at this
wavelength. Recent results on alloys of tantalum pentoxide and zirconium
dioxide are presented, which shows partial progress towards the same goal
whilst enabling the laser wavelength in the optical cavities to remain at
1064 nm.

Title: Understanding the origin of mass

The discovery of the Higgs boson in 2012 completed the experimental observation
of the particle content of the Standard Model. Since then, detailed measurements
of the Higgs boson properties and further searches for extended Higgs sectors
have been performed. These are crucial tasks both to complete our understanding
of this new particle, but also to verify the mass generation mechanisms
implemented in nature. The current status of this programme will be presented
and future directions will be discussed. Although the Higgs boson verified the
mechanism for mass generation for elementary particles, 85% of the mass in the
universe is in a form with an unknown nature that we call “dark matter”. The
status of the experimental searches will be presented, with emphasis on the
search for light Dark Matter being performed here at Birmingham.

Title: Artificial Neural Networks and Data Analysis

I will speak about pattern recognition using Artificial Neural Networks (ANN)
and SOM (SOM) (self-organizing maps).  First I define the input and output
patterns and the search of the dimension of the patterns. This requires to
look for the correlation length of the time series. I will define the training,
validation and learning error. The dimension of inputs patterns is defined by
the correlation length. The architecture is defined also by the number of input
neurons, layers and synaptic weights. The best architecture is found minimizing
the learning and generalization error studying the variation of the dependence
of these quantities on the possible choices a heuristic research. I will show
examples of networks with exact estimates of the learning error. The
minimization of the error can be performed, both theoretically and
experimentally only if the number of patterns is large. The case in which is
possible to show rigorously the theoretical result holds only for an infinite
number of patterns and infinite number of neurons.

Title: LISA, from on board measurements to Gravitational Wave Data Analysis

LISA (Laser Interferometer Space Antenna) is the future large mission L3 at ESA
(European Space Agency). It has been approved in 2017 after the success of the
technological demonstrator LISA Pathfinder and the detection of gravitational waves
(GW) by Ground-Based observatories LIGO -Virgo. The LISA Science Case is extremely rich
both for Astrophysics, Cosmology and Fundamental Physics: observations of Super Massive
Black Hole Binaries until very high redshift, Extreme and Intermediate Mass Ratio
Inspirals, Stellar Mass Black Hole Binaries, Galactic Binaries, Stochastic GW Background
from early Universe and various foregrounds, etc. While there is no critical technology,
LISA requires very high precision metrology and is a highly integrated instrument from
hardware subsystems until on-ground processing. Actually, before having data stream
usable for extracting GW sources, several processing steps have to be done both on-board
and on-ground, to suppress part of the noises.  In this talk, after a quick presentation
of the mission and an overview of the science case, I will present the LISA measurements
and the various processing applied to the data. Finally, I will present the current
status of the simulation, the Science Ground Segment including the Distributed Data
Processing Center and the Data Analysis Pipeline developed within the LISA Data
Challenge.

Title: Tests of general relativity with the binary black hole signals detected
by LIGO and Virgo

Binary black hole coalescences provide an excellent laboratory to search for
possible deviations from the predictions of general relativity (GR) in the
highly dynamical, strong field regime. Currently, a variety of tests for
deviations from the predictions of GR are applied to the waveforms from binary
black hole coalescences detected by LIGO and Virgo. These range from
consistency tests to checks for dispersion in gravitational wave propagation,
as would be caused by, e.g., a massive graviton. I will describe these tests
and their results when applied to the ten binary black hole signals detected
during the first two observing runs of the advanced gravitational wave
detector network: No evidence is found for deviations from the predictions of
GR, and we are able to place the most stringent constraints to date on possible
deviations from GR’s predictions for binary black hole coalescences.
Additionally, I will give initial results from an ongoing project investigating
the relation between these tests by applying them all to a suite of waveforms
exhibiting a variety of possible deviations from GR.

Title: Quantum optomechanics at room-temperature

Abstract: The Decades of advancement in technologies pertaining to
interferometric measurements have made it possible for us to make the first
ever direct observation of gravitational waves (GWs). These GWs emitted from
violent events in the distant universe bring us crucial information about the
nature of matter and gravity. In order for us to be able to detect GWs from
even farther or weaker sources, we must further reduce the quantum noise in
our detectors. In order to lower this quantum noise, GW detectors currently
use squeezed light. Squeezed light is a special quantum state of light which
has lower uncertainty in a certain quadrature, at the expense of higher
uncertainty in the orthogonal quadrature.

In this talk, I focus on using radiation-pressure-mediated optomechanical (OM)
interaction to generate squeezed light. Creating squeezed states by using
optomechanical interaction opens up possibilities for engineering truly
wavelength-independent squeezed light sources that may also be more compact and
robust than traditionally used non-linear crystals. Additionally, this project
inherently involves studying the OM interaction, which is the mechanism for
back-action noise in GW detectors. These observations are the first ever direct
observation of a room temperature oscillator's motion being overwhelmed by
vacuum fluctuations. More so, this is also the first time it has been shown in
the low frequency band, which is relevant to GW detectors, but poses its own
technical challenges, and hence has not been done before. Being in the
back-action dominated regime along with optimized optical properties has also
enabled us to observe OM squeezing in this system. That is the first direct
observation of quantum noise suppression in a room temperature OM system. It is
also the first direct evidence of quantum correlations in a audio frequency
band, in a broadband at non-resonant frequencies.

Title: Using 3D envelopes to better understand stellar structures and evolution

Asteroseismology has revolutionized our understanding of stellar structures and
their evolution, requiring better models to interpret the high-quality data
from current and future space missions. It is therefore crucial to go beyond
many of the simplifying assumptions that enter state-of-the-art stellar
evolution codes. For instance, it is well-known that the current treatment of
superadiabatic convection leads to a systematic offset in the predicted seismic
properties, when dealing with stars with convective envelopes. This is known as
the surface effect.

In order to mitigate this shortcoming, we have developed and validated a method
that allows our stellar evolution code to reliably mimic the mean stratification
of 3D simulations of stellar envelopes. Using our method, we are able to
completely overcome the structural contribution to the surface effect.
Furthermore, we find that the improved depiction of superadiabatic convection
in the outermost layers affects the evolution tracks. This has direct
implications for the inferred stellar parameters and hence for any field that
relies on a detailed understanding of stars, including exoplanet research and
the chemo-dynamical evolution of galaxies. Our results hence show how realistic
multi-dimensional simulations of stellar convection can contribute to answering
pressing questions in astrophysics.

Title: Computing and detecting gravitational-wave memory effects from
       binary-black-hole mergers

Gravitational waves from the mergers of ten binary black holes were detected in
the first two observing runs by the advanced LIGO and Virgo detectors; the total
number of detections is likely to double, at least, after the current observing
run. With this large number of increasingly precisely measured binary black
holes, the observations will reveal more subtle features in the gravitational
waves from strongly curved, dynamical spacetimes.

In this talk, I will discuss one such set of features, called gravitational-wave
memory effects, which are predictions of general relativity that are most likely
to be measured from systems with high gravitational-wave luminosities, like
binary black holes. These memory effects are characterized by lasting changes in
the gravitational-wave strain and its time integrals. I will describe how these
effects are related to symmetries and conserved quantities of spacetime. I will
also cover the computation of these memory effects and the prospects for
detecting them with current and planned gravitational-wave detectors. There
could be evidence for the memory effect in just a few years of advanced LIGO,
Virgo, and KAGRA data, although the precise timescale will depend upon the
properties of the population of merging binary black holes and the rate of
these mergers.

Title: Atom-by-atom engineering of novel quantum states of matter

The field of quantum simulators has flourished enormously during the last
decades, especially in the areas of nanophotonics and ultracold atoms.
Electronic quantum simulators, however, have not seen much progress.  Based on
a technique pioneered by the group of Manoharan for simulating graphene, we
show here how to design and characterize a Lieb lattice [1] and a Sierpinski
gasket [2]. Then, we explain how to modify their design to control the orbital
degree of freedom. Further tuning of the honeycomb geometry leads to the
emergence of topological edge states. In all cases, we observe an excellent
agreement between the theoretical predictions and the experimental results.
This technique is proving itself to be a very versatile framework for the
engineering and control of electronic systems, and is widening the perspectives
in the field.

Title: The CERN CLOUD experiment: Do cosmic rays influence Earth’s climate?

It was proposed in 1997 that cosmic rays could affect climate change based on an observed
correlation between the galactic cosmic ray flux and Earth’s cloud cover. The highly
controversial proposal was considered by many climate scientists to lack any physical
explanation. Nevertheless, as in the Wilson cloud chamber, ionization of the
atmosphere can create new cloud particles under the right conditions. The CERN CLOUD
experiment was designed to explore whether such an effect could provide a link between
cosmic ray ionization, clouds and climate. After about 8 years of measurements CLOUD has
made a series of breakthroughs in our understanding of how new aerosol particles are formed
in our atmosphere. I will describe these breakthroughs and answer the question in the title.

Title: Investigating fundamental physics using numerical simulations of black
       hole environments

Numerical simulations of binary black holes have gained much (well deserved)
attention since the LIGO detections of gravitational waves, where they are
used to provide templates for the signals produced during the merger
phase. However, the application of these now mature numerical techniques to
problems of fundamental physics is still a relatively new and underdeveloped
area of research.

Much of particle physics and cosmology concerns the behaviour of fields and
their excitations, with some well known examples being the Higgs field, or the
inflaton during inflation. The evolution of even the simplest fields in
strong, dynamical gravity environments is highly non trivial and generally
necessitates a numerical approach. I will describe two examples of how the
study of such fields around black holes may lead to the discovery of new
physics. Firstly, I will describe the behaviour of clusters of light bosonic
particles called axions, which are gaining popularity as dark matter candidates
 and their collisions with compact objects such as black holes and neutron
stars. Secondly, I will discuss the scattering of neutrinos by black holes,
and the information that the resulting interference patterns can give us about
the absolute neutrino masses.

Speaker: Yan-Chuan Cai, University of Edinburgh
Title: Cosmology and Astrophysics with the Cosmic Web

On large scales, the matter distribution of the Universe follows a web-like pattern, consisting of cluster, filament,
sheet and void. The cosmic-web shapes the formation of galaxies as their environment, and is strongly influenced
by the dark components of our Universe. It is the junction where astrophysics and cosmology meet. I will
summarise my recent research in this active frontier, focusing on the detection of missing baryons in filaments,
and the great opportunities and challenges for using clusters and voids to constrain cosmology.

As mentioned at a recent group meeting, Yan-Chuan Cai is visiting us on Feb 19-20, with a view to moving his
Royal Society URF from Edinburgh to Birmingham. Cai's research interests centre around the large scale structure
of the universe and devising novel tests of the cosmological model and gravity on very large scales. He uses data
from large optical surveys such as the Sloan Digital Sky Survey, the Kilo-Degree Survey, and the upcoming Dark
Energy Spectroscopic Instrument.

A few of us will be taking Cai out for dinner around 7pm on Tuesday, and we will also have lunch in Staff House on
Wednesday around 12noon. Please email me if you would like to join either or both of these gatherings.

There is also a programme of one-to-one meetings with Cai, to give more time for in depth discussion. There is
still space in the programme, so please let me know ASAP if you want meet with him. The most flexible times are
Tuesday afternoon and Wednesday morning. I encourage everyone, whether student, postdoc, or faculty to step
forward and meet with him, he's very engaging and keen to find out about the full range of research in our group.

I've also set aside 4-5pm on Tuesday for Cai to meet with postgrads without any postdocs or supervisors present.
This will be a nice low-key opportunity to tell Cai about your research and to get to know him and his research
too. I suggest that this gathering takes place in the ASR/PP coffee lounge, but am happy for the students to make
other arrangements. In the first instance, please chat among yourselves and/or just email me if interested, and
we/you can go from there. Graham Smith

Physics Colloquium

Speaker: John Sutherland - University of Cambridge.
Title: Origins of Life Systems Chemistry

How can chemistry morph into biology? This is the key question about the origin of life, be it on our planet several
billion years ago, or elsewhere and so we need to think about chemistry in the context of planetary science if we
want to know where we came from and whether or not we are likely to be alone in the Universe. The chemistry
used by biology to fabricate its various components is by and large hopelessly inefficient in the absence of
enzyme catalysts, so we need to look for different chemistry that can make the same componentry efficiently
without enzymes. But where do we look? One approach is to guess at the environment and then use laboratory
simulation to investigate its chemistry.

The problem with this is the guesswork – there were presumably many different environments on early Earth and
it is not obvious what chemistry they might be associated with. An alternative approach is to explore chemistry in
a pretty much unconstrained way to try and find out if all the molecules needed to kick-start biology can be made
under similar conditions from plausible feedstocks. If they can and the conditions required correspond to a
particular environment on early Earth then that environment is strongly implicated and can further guide
chemical investigations. In this lecture, I will present the results of this latter approach and demonstrate how
hellish conditions on Hadean-Archean Earth could have set the stage for the transition from chemistry to biology.

This is the only quantity with units of power, or luminosity, which can be

it is, in fact, the maximum possible luminosity for any physical process. I will
discuss the motivation for such a maximum luminosity conjecture and the
surprising link with black holes and event horizons. I will present the results
of a range of calculations designed to test the robustness of this conjecture.

Title: The supernova that made us rethink stellar evolution and binary stars:
       Supernova SN 1987A

It has been nearly 32 years since the discovery of the most-well observed
supernova in history: SN 1987A , that exploded in the Large Magellanic cloud.
It belonged to the most commonly occurring type of supernovae (a Type II event)
, but its peculiarity made us relook at the physics of stellar evolution and
supernovae explosions. The progenitor identified for SN 1987A was not a red
supergiant as expected from standard theory at the time, but a blue supergiant.
The observational signatures of this blue supergiant indicate that it could
have evolved from the merger of a massive binary system, providing evidence
that such mergers do take place. We know from massive star surveys that nearly
30-40% of all interacting binaries are expected to merge. This talk will focus
on the evolution of the progenitor of SN 1987A from a binary merger scenario,
and present the first set of stellar evolution models that can simultaneously
match the progenitor and the light curve of the supernova.

Athira is visiting us from Monday 4 February until Thursday this week. Athira
has been working on binary star mergers, and in particular the origin of the
(in)famous supernova 1987A. She completed her PhD in Monash (Australia) with
the supervision of Alex Heger. She's currently working with Selma de Mink on

Diamond is not only the king gemstone, but also a promising material in

show unique coherence properties under ambient conditions. Their quantum
state can be readout and manipulated using a combination of single molecule
spectroscopy and magnetic resonance techniques. In this talk I will discuss
the potential of atomic magnetometers based on single color centers for
nanoscale sensing and imaging. New photoelectric detection technique allowing
efficient readout of single color centers will be discussed.

Title: The exciting life of old stellar clusters

Globular clusters are among the oldest and brightest structures in the
Universe, and are therefore witnesses of processes from the early up to the
present-day Universe. In turn, they play a major role in the benchmark for
stellar evolution theory and they are used to constrain the assembly histories
of galaxies. Over the last decades, several pieces of ground-breaking
observational evidence were accumulated pointing out the presence of multiple
stellar populations with different chemical compositions in every individual
globular cluster studied in detail so far. I will review the effects of
chemical features typical of these multiple populations on the evolution of
stars and I will show their impact on the properties of their hosting cluster.
Finally, I will briefly discuss their effect at larger scales on external
galaxies.

"Stripped envelope supernovae and where they come from". Additionally, a
reminder that the next ASR group meeting is on February 6th, featuring
the first of the 2nd year PhD talks, and will continue with its usual bi-weekly
cadence. Matteo

Core collapse supernovae are the endpoints in the evolutionary history of some
massive stars. A significant fraction of them are observed as type Ib and type
Ic SNe, indicating that some process must have stripped them from their
hydrogen envelopes, and of their helium envelopes as well in the case of type
Ic SNe. Evolutionary scenarios involving single stars have a difficult time
explaining the properties of these SNe, and binary evolution seems to be the
preferred path. They are also related to more “exotic” events such as GRBs,
X-ray binaries, hypernovae and gravitational wave sources. I will review the
recent work we’ve done in the Bonn stellar group trying to understand where
SNe type Ic come from, along with some other transients that occur in similar
systems, and discuss some difficulties in understanding massive stars in
general.

Title: The Hydrangea simulation project: how common is satellite disruption
       in galaxy clusters?

 Galaxies in groups and clusters are subject to a variety of environmental
influences that can affect their evolution, such as ram pressure stripping,
encounters with other galaxies, and tidal mass loss. The Hydrangea
simulations are a spin-off from the EAGLE project designed to study these
processes and their expected imprints on the cluster galaxy population. I
will introduce these simulations and highlight some successes – and failures
– that have emerged from comparison to observations. To illustrate the insight
that can be gained from them, I will then discuss what they predict about the
fate of satellite galaxies in clusters (and groups): are they disrupted
rapidly after accretion, or can they survive in the harsh cluster environment?

Code Review Meeting

Thursday 31 January 2019, 11am, Physics West Library

For those of you who haven't heard about the meeting yet, the idea behind
code review is to have a meeting dedicated to discussing code rather than
science, since for a lot of us coding is an important part of our
methodology and gets mostly overlooked.

The default format is for someone to present some ~100 lines of code they've
been working on (doesn't have to be finished!), which other people can comment
on or ask questions about. We've found this naturally leads to discussing
tools, best practices or style. More eyes mean it's easier to find bugs as
well!

I mentioned it's a python code review meeting (which is because I'm personally
biased, I readily admit this). We like to keep it to one language that all
attendees as familiar with, so that anyone present can participate. That
said, we welcome people with any level of python expertise; ideally if you're
less familiar you can learn from people with more expertise, and if you're
more experienced you can learn by explaining or from the discussions.

If you're interested in joining, please ask David to be on the mailing list
(codereview@star.sr.bham.ac.uk) and join the mattermost channel, and/or just
show up to the next meeting. Most announcements are made on mattermost/the

Current formation models predict both massive black hole binaries and
stellar-origin black hole binaries to have significant eccentricities
when they enter the LISA band. Different formation scenarios also
predict different spin magnitude and spin alignment distributions. In
order to be able to discriminate between those models, it is important
to have fast and accurate waveforms that model eccentric systems with
misaligned spins. We will present an inspiral model in the Fourier domain
that could be used to perform such studies.

Title: Antennas for Molecules

Detection of individual molecules is commonplace in biology and chemistry
for nanoscale imaging and tracking.  Unfortunately, the dependence on
fluorescence comes with low signals and slow dynamics. Optical (nano)
antennas can help to brighten up molecular signals. Here first, I will
show how nanoscale control of molecule-antenna interaction gives 100-1000
times enhancement, high real space resolution (20-40 nm), very faster
radiative decay on picosec timescale and even strong coupling. Single
biomolecules, which otherwise are simply invisible, become discernible.
Next, I will show how combination with tailored ultrafast femtosecond
pulses allows following excited state vibronic dynamics and energy
transfer, all at the level of a single molecule. These nanophotonic
technologies allow uncovering the nature of nanoscale ultrafast energy
transfer in natural light-harvesting system in their ambient conditions.

Title: X-rays across the galaxy population: tracing star formation and AGN
       activity

Abstract - I will present new work from a series of papers that combines large
samples of galaxies with deep Chandra X-ray data to measure the distribution
of X-ray luminosities across the galaxy population, using a sophisticated
Bayesian technique. Our measurements allow us to trace two origins of the
X-ray emission: star formation and AGN activity.
 
At low luminosities, we identify narrow peaks that we associate with star
formation processes (tracing the combined emission from X-ray binaries
throughout the galaxy). By tracking the position of these peaks as a
function of stellar mass and redshift we provide new, independent measurements
of the galaxy “star-forming main sequence”, based on the X-ray emission.

We also identify a tail in our distributions to higher X-ray luminosities that
allows us to trace the incidence of AGN. We use these data to measure the
distribution of AGN accretion rates across the galaxy population, as a
function of stellar mass, redshift and star formation rate. Our results reveal
a broad distribution of accretion rates in all galaxy types, reflecting the
flickering of AGN accretion on short timescales relative to the evolution of
galaxy properties. In star-forming galaxies, we find a broad correlation
between the star formation rate and the incidence of AGN (traced by the
fraction of galaxies with AGN and the average specific accretion rates),
indicating the key role of cold gas in AGN fuelling. We also measure the
AGN incidence in galaxies with a wider range of star formation rates at a
fixed stellar mass, spanning the star-forming main sequence and quiescent
galaxy populations. These measurements show enhancements in the incidence of
AGN and reveal the variety of mechanisms that drive black hole growth across
the galaxy population.

Speaker: Tim Bedding, University of Sydney
Title: A Golden Age of Asteroseismology with Kepler

Abstract - Stellar astrophysics has entered a new golden age, thanks to
wonderfully precise measurements being returned by NASA ’s Kepler mission.
Kepler is a 0.9-metre space telescope that has been monitoring the brightness
of more than 100,000 stars with extraordinary accuracy for more than four
years. Its main goal is to discover extra-solar planets by detecting the small
dips in light as they transit their parent stars. The mission has been
spectacularly successful, with thousands of candidates reported. Meanwhile,
Kepler’s observations of oscillations in thousands of stars have led to a
revolution in asteroseismology. I will review key results which include
detecting gravity modes in red giant stars and characterizing stars found
to host exoplanets. Results from ESA ’s Gaia mission will add to the
excitement, as has the launch of TESS , which is an all-sky follow-up mission
to Kepler .

Code Review Group

Monday 8 October 2018, 11am, Physics West Library

Code review is the practice of getting together to talk about code. As
scientists, we tend to talk about the science that goes into our code, but
skip over the implementation, even though this is a significant part of what
we spend our time doing. Talking about line to line code is an effective way
of spotting bugs, improving style and documentation, and learning new coding
practices. 

Our group is for anyone who programs in python and wishes to improve, whether
you are a beginner or experienced coder. The group benefits from having a
range of experience levels and different topics of coding expertise. We have
weekly meetings of one hour where we usually look at a piece of code one of us
is working on.  If this sounds like the thing for you, please come talk to me
or send an email (jgoldstein@star.sr.bham.ac.uk).
Requirements are that you try to attend most of the meetings, and you will
have to take a turn presenting at some point (no preparation needed, though).
Obviously feel free to just come to one of our meetings to see if you like it.
Apologies if you'd like to join but are not interested in python specifically,
we have tried doing other languages in the past but we found it's not very
effective if not everyone actually reads whichever language we do. Since I'm
a python programmer we are completely biased towards that  ̄\_(ツ)_/ ̄ Janna Goldstein

Title: Jupiter’s interior revealed by Juno

The giant planets of our Solar system were the first planets to form and the
most influential ones. Their interiors and atmospheres have crucial information
to understand the origins of the Solar system and of our own Earth.
With the aim to reach a deeper understanding of Jupiter’s interior and
atmosphere, the Juno spacecraft was sent to the biggest giant in the Solar
system, and its results have fundamentally changed our understanding of this
planet. In this colloquium, I will show the models we use to understand
Jupiter's interior and our latest Juno results, including a much deeper
understanding of Jupiter’s interior and jet streams. This is helping us to
reach a better understanding of Jupiter’s formation history, and of our solar
system’s.

NOTE THE CHANGE OF TIME
Speaker: Dr Fiorenzo Vincenzo, Hertfordshire

Title: Galactic astroarchaeology with cosmological chemodynamical simulations.

The chemical composition of the interstellar medium of galaxies continuously
evolves as a function of time because of many environmental physical processes.
Restitution of metals from dying stars, astration of metals due to the star
formation activity, gas inflows and outflows, radial mixing of both gas and
stars are all fundamental mechanisms which drive the chemical evolution of
galaxies. Starting from the observed present-day chemical abundances in the
stars and interstellar medium, chemical evolution models aim at reconstructing
the past chemical enrichment history of galaxies, in a typical
“astro-archaeological” approach. 

In the first part of the talk, I will introduce the basic concepts behind
chemical evolution models and present my original contribution in the
foundations of this field. In the second part, I will show how cosmological
hydrodynamical simulations can be effectively used to study the evolution of
the radial (gas-phase and stellar) C, N and O chemical abundance gradients in
galaxies, presenting also new results from high-resolution zoom-in simulations,
where a target galaxy is selected at low redshift from a reference large-scale
cosmological simulation and then re-simulated with a larger number of
resolution elements, starting from the initial conditions of the early
Universe. Finally, I will present some preliminary results from the
chemodynamical simulation of a Milky Way-like galaxy, that we have developed
to characterise the different chemical evolution histories of the thin and
thin disc stellar components of our Galaxy.

Speaker: Dr Martin Fullekrug, University of Bath
Title: Lightning into Space

The recent discovery of lightning into space and brief illuminations above
thunderclouds have attracted the broadest interest by the public media. These
illuminations are termed sprites, gigantic jets, elves, halos, and blue jets.

Sprites for example, are reddish illuminations of the Earth's atmosphere
ranging from 40-80 km height and extending up to 50 km in width. Sprites are
seen above the largest thunderstorms on planet Earth, and they are mainly
initiated by super strong lightning flashes to the ground. Recent research on
sprites focused on their impact on the Earth's atmosphere and in particular
on the possibility to be associated with natural particle accelerators above
our heads. A sophisticated camera was just installed on the International
Space Station on April 13th this year to unravel the mysteries of lightning.

These novel phenomena demonstrate that the area above thunderstorms is one of
the least well known 'terra incognita' of the Earth's atmosphere and many more
discoveries are expected in the years to come.

Title: The surprising impact of gravity waves

Gravity waves are low frequency fluid oscillations restored by buoyancy
forces in planetary and stellar interiors.  Despite their ubiquity, the
importance of gravity waves in evolutionary processes and asteroseismology
has only recently been appreciated. For instance, Kepler asteroseismic data
has revealed gravity modes in thousands of red giant stars, providing
unprecedented measurements of core structure and rotation.

I will show how gravity modes (or lack thereof) can also reveal strong
magnetic fields in the cores of red giants, and I will demonstrate that
strong fields appear to be common within “retired” A stars but are absent
in their lower-mass counterparts. In the late phase evolution of massive
stars approaching core-collapse, vigorous convection excites gravity waves
that can redistribute huge amounts of energy within the star. I will present
preliminary models of this process, showing how wave energy redistribution
can drive outbursts and enhanced mass loss in the final years of massive
star evolution, with important consequences for the appearance of
subsequent supernovae.

Title: How many pixels does your camera have? How many does it need?

Cameras are often marketed in terms of the number of pixels they have – the
more pixels the “better” the camera. Rather than increasing the number of
pixels we ask the question “how can a camera work with only a single
pixel?”. This talk will link the field of computational ghost imaging to
that of single-pixel cameras explaining how components found within a
standard data projector, more commonly used for projecting films and the
like, can be used to create both still and video cameras using a single
photodiode.

Such single pixel approaches are particularly useful for imaging at
wavelengths where detector arrays are either very expensive or even
unobtainable. The ability to image at unusual wavelengths means that one can
make cameras that can see through fog or smoke or even image invisible gases
as they leak from pipes.

Beyond imaging at these unusual wavelengths, by adding time resolution to
the camera it is possible to see in 3D, perhaps useful for autonomous
vehicles and other robotic applications.

Title: Quantum Entanglement + Deep Learning = Gravitational Waves + Cosmography

The recent pile of black hole mergers has signalled the birth of gravitational
astronomy. Just as the Jyotisha and Gan De eventually lead to Galileo, we too
can look forward to dramatic improvements in what is measurable with
gravitational waves.

I will describe how we can utilize coherent quantum feedback to bypass the
Poisson limits in interferometry, and modern neural networks to remove
terrestrial interference. This imminent increase in our astrophysical reach
should allow for high precision probes of black hole horizons and high fidelity
maps of the shape of the universe.

Title: White dwarf-neutron star and white dwarf-black hole binaries
Binaries containing a white dwarf and a neutron star are interesting for a
number of reasons. Their existence and properties allow us to constrain the
evolution of interacting binary stars, probing a number of important
poorly-understood physical processes such as common-envelope evolution and
neutron-star kicks. They may be observable with the LISA gravitational-wave
experiment. Following gravitational-wave emission, their merger may produce
luminous transients, and they are a possible candidate progenitor for
calcium-rich “gap” transients. I will discuss the theory of their formation
and of their ultimate destruction after gravitational-wave inspiral. I will
also touch on their more massive relatives, containing a white dwarf and a
black hole, and attempt to convince you that we have good evidence for the
existence of such a binary in the globular cluster 47 Tucanae.

Black-hole driven processes in the Universe are now accepted to play a key
role in the evolution – perhaps even formation – of galaxies, the cataclysmic
death of massive stars and ultimately the production of gravitational waves
and, perhaps, heavy elements.

In this talk, I will present recent studies of stellar and supermassive black
holes systems; I will show the ubiquity of fast outflows, the importance and
role of magnetic fields and present prospects for future work in the era of

Title: Satellite observations of Atmospheric Composition

Abstract:

Atmospheric composition (i.e. trace gases and aerosols) has been observed
from space since the 1970s. Early observations focussed on the stratospheric
ozone layer but there has been an increasing emphasis on the more
challenging lower atmosphere in recent decades. The global, long-term
coverage provided by satellites has greatly changed our understanding of the
dynamics and chemistry of the atmosphere and our ability to tackle major
environmental science questions.
 
In this talk I will briefly summarise the different approaches used to
observe the atmosphere from space – e.g. different viewing geometries (limb
versus nadir), wavelength regions (microwave, IR, visible, UV) and
techniques (emission, absorption). Then, I will focus on the application of
the data, in conjunction with detailed numerical models, to address key
environmental issues such as the depletion of stratospheric ozone layer,
climate change and near-surface air quality.

Title: Causal Sets, Discrete Gravity

Abstract: Quantum gravity is the name of a problem, not a theory. The problem
is that we do not have a unified framework for fundamental physics in which
both gravity and quantum theory are incorporated. Causal Set Theory is an
approach to the problem based on the hypothesis that spacetime is fundamentally
discrete or atomic. I will explain the motivation behind this approach and map
out some of the frontiers of current research in the area. I will describe how
causal set theory has already had one empirical success and suggest that more
may be coming as the standard cosmological model (Lambda-Cold-Dark-Matter)
comes under pressure from more data.

Abstract: On 17 August 2017, the LIGO-Virgo gravitational wave observatories
detected a compact binary merger with a difference: for the first time, the
component masses were consistent with neutron stars rather than black holes.
Moreover, the Fermi satellite simultaneously detected a short gamma-ray burst
from a consistent sky position, marking the beginning of joint GW-EM astronomy.
I will describe our discovery of the optical counterpart using the Dark Energy
Camera, and subsequent follow-up in optical, infrared, UV, X-ray and radio.
The wealth of data reveals multiple emission components including a relativistic
jet and the first clear evidence for a radioactive ‘kilonova’ comprised of
r-process ejecta, proving that neutron star mergers are a key source of the
heaviest elements. I will show how our modelling of the transient and its host
galaxy sheds light on the physical conditions in the system and its pre-merger
history.

science) have been revolutionized by detector technologies that were developed
for high energy physics.

Title: Zeeman-Doppler studies and the rotation evolution of low-mass stars

One of the most important and fundamental properties of low-mass main sequence
stars is their rotation period.  It is known to correlate with numerous proxies
of magnetic activity such as X-ray emission, surface magnetic field strengths
and stellar winds. In turn, stellar winds are the main agent of mass- and
angular momentum-loss over the main sequence lifetime, causing the rotation
period to increase as the star ages. While the mechanisms driving stellar winds
are not precisely known, the stellar magnetic field must play an important role.
One way in which the magnetic fields of other stars can be studied is via the
Zeeman-Doppler imaging technique.  This technique is capable of mapping the
large-scale magnetic field topology at stellar surfaces of other stars. To
date, ~100 stars have had their surface magnetic fields mapped with this
technique providing new insights into how the magnetic fields of cool dwarfs
vary with parameters such as stellar mass and rotation. In this talk, I will
discuss some of these trends, as well as the implications for stellar rotation
evolution along the main sequence.

Title: The Gravitational-Wave sky so far

In less than two years of operation, gravitational-wave observatories –
Advanced LIGO, and more recently Virgo – have directly detected
gravitational waves, discovered binary black hole mergers, revealing an
abundant population of these systems, and recently observed the first binary
neutron star coalescence. The aftermath of this event was also observed
across the electro-magnetic spectrum, from gamma rays to radio waves,
providing evidence that binary neutron star mergers are engines behind (at
least some) short gamma ray bursts and primary production sites of elements
heavier than iron in the Universe. I will summarise the results so far,
their main implications and touch upon prospects for the future.

Title: Open questions in the formation of binary stellar systems containing
       black holes

The recent detection of gravitational waves from coalescing binary black
holes by LIGO allowed for the first time the direct observation of
stellar-mass black holes. These gravitational wave detections, complemented
by a 45-year-long history of indirect observations of black holes in X-ray
binaries, can give us now a more complete picture of the formation and
evolution of binary stellar systems containing black holes. Yet, to date, a
number of physical processes involved in the formation and evolution of
these systems remain poorly understood. In this talk, after briefly
reviewing our current understanding of the evolutionary channels leading to
the formation of black-hole binary, I will discuss the some of the main
uncertainties involved in these formation scenarios: the occurrence of
natal kicks during the core-collapse phase leading to black-hole formation,
the angular momentum content of the formed black holes and the phase of
dynamically unstable mass-transfer also known as common envelope. Finally,
I will present an outlook of how we can improve, in the near future, our
understanding in all these fronts.

Speaker: Ilya Nemenman, Emory University, USA
Title: The physics of cellular sensing

For many years, biology was the refuge from mathematics within the
scientific world. This is no longer true. The last two decades have
witnessed an explosive growth in life sciences, fuelled largely by
quantitative, mathematical reasoning and high-precision experiments
that originated in physical sciences. The times of summarizing
components of biological systems with cartoon diagrams that many of
us remember from high school biology text books are giving way to
quantitative models that make predictions as precise as those in the
inanimate physical world.

In my talk, I will try to guide you through 30+ years of developing
such quantitative models for one relatively simple function that all
living systems must perform to survive in this world: sense their
environment. We can characterize such sensing by living cells in the
same terms as we use to describe man-made information processing
devices. Surprisingly, this leads to the realization that even
“simple” cells are extremely good in sensing tasks, approaching
fundamental physical limits set by molecular diffusion and
thermodynamics, and beating most human-engineered devices. And where
the achievable performance is not sufficient, cells have found
ingenious ways of improving it by comparing their notes to those of
their neighbours, by sharing the workload, by multiplexing their
communications, by trading energy for extra bits of information, etc.
I will illustrate some of these mechanisms with examples from the life
of bacterial and mammalian cells.

Title: Climate Change and Food: A Cosmologist’s Perspective

There is an impending perfect storm of pressure on our food production system,
with increasing population and changing consumer tastes, in the face of rising
temperatures and extreme weather events. Tim Gore, head of food policy and
climate change for Oxfam, said “The main way that most people will experience
climate change is through the impact on food: the food they eat, the price
they pay for it, and the availability and choice that they have.”. Yet, at the
same time, food production is a bigger contributor to climate change than
transport. This is why I am leading the new STFC FoodNetwork+ which aims to
engage STFC researchers (astro/particle/nuclear physics) and STFC facilities
(e.g. Diamond) to apply their capabilities to food, from agriculture, supply
chain to nutrition and consumer choice. In this talk I will describe some of
the challenges in food research and how physicists can help.

Title: MIGA and GW detection with atom interferometry at low frequency

Atom interferometry has been proposed for the realization of GW detectors in
the infrasound band (10 mHz - 10 Hz) [1]. Such frequency band is forbidden to
current ground based GW detectors due to low frequency gravity gradient noise
that causes a tidal effect on the suspended mirrors used as test masses to
detect gravitational radiation. Adopting as probes arrays of atom clouds in
free fall and interrogated simultaneously in a gravity-gradiometer
configuration allows the suppression of Newtonian Noise [2], enables low
frequency sensitivity, and opens the way toward the realization of infrasound
GW detectors on Earth. In this framework, I will report on the MIGA project [3]
, whose target is to build a demonstrator for GW detection using atom
interferometry in the underground environment of LSBB (Rustrel, France).

Title: Uncovering the First Stars

The Epoch of Reionization (EoR) signals the end of the Dark Ages of the
Universe and the birth of the first stars.  The race is on to make the first
statistical detection of this epoch however the foregrounds swamp the
cosmological data by several orders of magnitude and their removal remains a
significant challenge for both current and future telescopes. I will speak
broadly about the foreground mitigation techniques currently being used with
EoR data, with a focus on blind source separation techniques. Overcoming the
challenges such as the huge foregrounds has not been merely an inconvenience
on the way to the prize ... The Square Kilometre Array (SKA) is due to be
built in 2019 and it is vital we embed the lessons learned
from the current EoR experiments before the design of the instrument is
finalised. I will introduce the software OSKAR that I have helped develop in
order to simulate EoR data, such that we can test design options and truly
exploit the incredible power of the SKA.

Title: Making waves in biomedical optics

Several hallmarks of cancer, such as aberrant metabolism, are associated with
highly aggressive disease and poor prognosis. These hallmarks lead to changes
in tissue optical properties that can now be detected non-invasively thanks to
technological advances emerging from telecommunications and remote sensing. In
this talk, I will first provide an overview of the metabolic processes of
interest to our laboratory, particularly in the context of the tumour
microenvironment. I will then detail the technical development of several new
imaging modalities that have the potential to increase early cancer detection
and also improve patient stratification. In each case, I will provide examples
of their biomedical application in living subjects.

Title: (Ex-?) Binary stars in the Galactic thick disc

Recent studies of old stars in the Galactic thick disc suggest it contains a
population of “young” giant stars. These are chemically and kinematically
members of the thick disc, but their masses – measured by asteroseismology –
are up to a factor of two greater than expected given the age of the thick
disc. Galactic astronomers have suggested they come from a population of stars
that have migrated from the bar of the Galaxy. Because migration away from a
bar is anathema to us, we show that they could instead be (ex-?)binary stars.
These stars have undergone mass transfer, a process similar to that which
forms blue stragglers in globular clusters, or they have merged. Through the
carbon–to–nitrogen ratio we relate stellar surface chemistry to stellar mass
using single and binary star models. The latter match the observations far
better than we could have expected. We also predict binary fractions and other
properties of these “young” stars ready for comparison with ongoing and
upcoming observational programmes.

Title: Thermonuclear burst oscillations: where firestorms meet fundamental
physics


Neutron stars offer a unique environment in which to develop and test
theories of the strong force. Densities in neutron star cores can reach up
to ten times the density of a normal atomic nucleus, and the stabilising
effect of gravitational confinement permits long-timescale weak
interactions. This generates matter that is neutron-rich, and opens up the
possibility of stable states of strange matter, something that can only
exist in neutron stars. Strong force physics is encoded in the Equation of
State (EOS), the pressure-density relation, which links to macroscopic
observables such as mass M and radius R via the stellar structure equations.
By measuring and inverting the M-R relation we can recover the EOS and
diagnose the underlying dense matter physics.

One very promising technique for simultaneous measurement of M and R
exploits hotspots (burst oscillations) that form on the neutron star surface
when material accreted from a companion star undergoes a thermonuclear
explosion (a Type I X -ray burst). As the star rotates, the hotspot gives
rise to a pulsation. Relativistic effects then encode information about M
and R into the pulse profile. However the mechanism that generates burst
oscillations remains unknown, 20 years after their discovery. Ignition
conditions, flame spread, and the magnetohydrodynamics of the star's ocean
all play a role. I will review the progress that we are making towards
cracking this long-standing problem, and establishing burst oscillations as
a tool par excellence for measuring M and R. This is a major goal for future
large area X-ray telescopes such as eXTP and STROBE -X.

The ALMA image of HL Tau is only one of the many spectacular images of
protoplanetary disks obtained during the last five years. With specific
focus on near-IR scattered light images from VLT /SPHERE, I show how these
observations are changing our view of the processes of the planet formation.
It turned out that peculiar features like spirals, rings, shadows, and
cavities are ubiquitous in disks. The increased number of observations
allows us now to draw the first conclusions on the evolution of disks and
their interaction with (forming) planets.

screening mechanisms, which allows these scalars to have interesting
cosmological effects whilst remaining compatible with terrestrial and solar
system tests of gravity. I will then go on to discuss prospects for
detecting these fields, and explain why our best hope of learning more about
dark energy may be with table top scale experiments.

Title: Determining Big G and the Art of Measuring Small Forces

The Newtonian constant of gravitation, or Big G, is arguably the mostr
frustrating fundamental constant of Nature to measure. Cavendish first
measured Big G in 1798 with an uncertainty of about 1%. After two centuries
of scientific development the uncertainty of G has only fallen by two orders
of magnitude, and many experiments produce conflicting results. By comparison,
in just over one century the Planck constant was both theorised and then
measured with an uncertainty of just twelve parts per billion.

Big G is so hard to measure as the gravitational coupling between matter is so
weak, but with measurements disagreeing by over 10 sigma it is clear something
more has gone awry. We have to wonder, are we seeing effects of undiscovered
physics, or are we simply chasing down the mistakes of other researchers? A
history of improperly calibrated electrostatic servos, unaccounted
anelasticity, and unnoticed Abbe errors have plagued mechanical balances of
the past. With atom interferometer measurements poised to steal the show, or
at least add more results into the fray, NIST is adopting a different approach.
Instead of building a new experiment we are acquiring, investigating, and
repeating suspect experiments to shed light on what is causing the
discrepancies.

We have taken the BIPM torsion balance (currently measuring 9 sigma above the
CODATA recommended value) and placed it on a state of the art coordinate
measuring machine housed in the NIST advance measurement laboratory,
surrounded by world leading calibration laboratories. We are expecting a new
measurement of Big G to be completed in 2017, both with the original copper
source masses and new single crystal sapphire masses.

In this talk I will outline the experimental challenges of performing accurate
measurements of small forces, from atomic force microscopy to optomechanics,
before concentrating on the NIST's new measurement of Big G.

Title: Cryogenic LIGO Test Masses for Next Generation Gravitational Wave Observatories

Abstract:
Now that the 2nd generation of LIGO, Advanced LIGO, is running and making
gravitational wave observations, plans for the 3rd generation are now in
development. The 3rd generation, known as LIGO Voyager, intends to
improve upon Advanced LIGO’s sensitivity by a factor of 3 over a broad
frequency range, increasing the rate of gravitational wave detections by
more than an order of magnitude. One of the proposed upgrades to realize
this improvement involves cooling silicon mirror test masses to cryogenic
temperatures to reduce the thermal noise in the the mirror coatings and
the mirror suspensions. This talk discusses a method to cool these mirrors
to 120 K without compromising the strict vibration isolation requirements.
Recent results and ongoing experimental work from the LIGO group at Stanford
University will be shown.

observables such as mass M and radius R via the stellar structure equations.
By measuring and inverting the M-R relation we can recover the EOS and
diagnose the underlying dense matter physics.

One very promising technique for simultaneous measurement of M and R
exploits hotspots (burst oscillations) that form on the neutron star surface
when material accreted from a companion star undergoes a thermonuclear
explosion (a Type I X -ray burst). As the star rotates, the hotspot gives
rise to a pulsation. Relativistic effects then encode information about M
and R into the pulse profile. However the mechanism that generates burst
oscillations remains unknown, 20 years after their discovery. Ignition
conditions, flame spread, and the magnetohydrodynamics of the star's ocean
all play a role. I will review the progress that we are making towards
cracking this long-standing problem, and establishing burst oscillations as
a tool par excellence for measuring M and R. This is a major goal for future
large area X-ray telescopes such as eXTP and STROBE -X.

arbitrary limit? Is it a constant of Nature, a complexity bound or an
artefact of human mind? I'll review several recent attempts to give it a

Title: Detection and follow-up of fast radio bursts

Fast radio bursts (FRBs) are quickly becoming a subject of intense interest
in time-domain astronomy. FRBs have the exciting potential to be used as
cosmological probes of both matter and fundamental parameters, but such
studies require large populations. Advances in FRB detection using current
and next-generation radio telescopes will enable the growth of the population
in the next few years. Real-time discovery of FRBs is now possible with 6
sources detected in real-time within the past 2 years at the Parkes telescope.
I will discuss the developing strategies for maximising real-time science with
FRBs including polarisation capture and multi-wavelength follow- up.
Particularly, I will focus on the real-time detections of four new sources
that provide a test bed for fast radio burst science. I will also discuss how
our response to these events can inform next generation surveys and pave
the way for the enormous number of FRB discoveries expected in the SKA era.

Title: Tianqin Mission - space-based gravitational waves detection

TianQin is a proposal for a space-borne detector of gravitational waves in the
millihertz frequency range. The experiment relies on a constellation of three
drag-free spacecraft orbiting the Earth. Interspacecraft laser interferometry
is used to monitor the distances between the test masses that are moving along
geodesics. The experiment is designed to be capable of detecting a signal with
high confidence from a single source of gravitational waves within a few
months of observing time. In this talk, I will introduce the preliminary
mission concept for TianQin, including the candidate source and experimental
designs. I will also present the progress on developing key technologies and
the roadmap of whole mission. We expect TianQin to be flown in the second half
of the next decade.

Title: The Large Robotic Telescope: a facility for the new era of time domain
       astronomy

The Liverpool Telescope is a fully robotic, 2-metre class optical/infrared in
operation on the Canary island of La Palma. The rapid response and flexibility
of robotic telescopes make them ideal tools for study of the time variable sky.
With the field of time domain astronomy set to be revolutionised by new
discovery facilities such as LSST, plans are being made in Liverpool for a new
robotic telescope to capitalise on this new era. This facility has the working
title 'Liverpool Telescope 2' or the 'Large Robotic Telescope' and we aim to
have it in operation on La Palma by ~2022. The core goal of the facility will
be the follow-up of transients.

The current generation of optical surveys have opened up a new era of
transient astronomy, but at the same time have introduced a new problem: our
discovery capability has dramatically outpaced our follow-up capacity, such
that less than 10 per cent of new transients receive a spectroscopic
classification, let alone any scientific exploitation. The follow-up gap is
going to increase in size by orders of magnitude as we move into the LSST era.
The same problem is inherent in the gravitational wave follow-up programme,
the uncertainty in the sky position of any Advanced LIGO / Virgo detection is
of the order of degrees. Surveying this error box is not the biggest problem
in identifying an electromagnetic counterpart: the real challenge is
distinguishing the counterpart from the many unrelated transient events in
the region. The Large Robotic Telescope will be designed for the follow-up
role: a fully robotic 4-metre telescope with a lightweight, fast-slewing
design, providing a world-leading rapid response capability for efficient
programmes of classification spectroscopy and the follow-up of fast-fading
sources. In this talk I will detail the science case and provide an update
on development of this new telescope.

As part of our AHRC-funded project you are cordially invited to a focus group

Such journals are typically very large, with a broad subject scope and
operating an open access publishing fee. They also tend to operate a peer
review system that seeks to evaluate only the scientific soundness of papers,
rather than their potential impact or importance to the field. Well known
mega-journals include PLOS ONE, Scientific Reports and Sage Open.
We do not expect participants to know about specifics of mega-journals, or
indeed even to have heard of them.

We want to know:
- Where you publish and why?
- Have you already published in a mega-journal, or would you consider it in
  the future?
- What constitutes 'scientific soundness', and should editors and reviewers
  be filtering for significance to the discipline?

Title: More than a theory - connecting highly evolved stars with their younger
selves through space based asteroseismology

Within the last 10 years and at an accelerating pace, space-based observations
have been exposing the interiors of stars at all stages of their development.
The number of stars subject to these studies range from dozens to thousands
depending on the specific type of star. Prior to this era, our studies relied
on in-depth study of individual targets, mostly subject to the handicap of
observing from a rotating, cloud-dotted platform. In this talk, I'll discuss
several recent revelations about how stars evolve after they've left the main
sequence. In particular, we'll look at what the Kepler and K2 missions have
revealed about the interior structure of white dwarfs and core helium-burning
sdB stars – and how internal properties these geriatric stellar types are
connected with their red giant predecessors.

Singing binaries: listening to the chirps of black holes

In this lecture, Professor Mandel will discuss the detection of gravitational
waves and explore the potential research opportunities arising from this
revolutionary discovery.  On September 14, 2015, the instruments of the Laser
Interferometer Gravitational-wave Observatory (LIGO) detected a disturbance.
This tiny signal was the echo of a very loud song, sung by a pair of black
holes merging more than a billion years ago during the last fraction of a
second of their lives. This discovery heralded the conclusion of a
decades-long search for one of the most difficult to test predictions of
General Relativity, Einstein's theory of gravity.

At the same time, this black-hole was the first note of a beautiful symphony
to reach us through a newly opened window on the Universe. Through this window
of gravitational-wave astronomy, we are already beginning to probe the secrets
of strong-field gravity. In the next few years, we anticipate hearing many
more songs coming from the mergers of compact remnants of massive stars:
neutron stars and black holes. Like palaeontologists who use the skeletons of
dinosaurs to discover what living dinosaurs looked like, we are beginning to
study the evolutionary history of massive stars by observing their merging
remnants.

Speaker: Dr Richard Stainsby, National Nuclear Laboratory
Title: Generation IV Reactors: Opportunities and Challenges

Generation IV reactors offer the promise of reliable, low-carbon, on-demand,
safe and economic nuclear energy which has the potential to be sustainable
for millennia. Closing the nuclear fuel cycle such that 96% of the material
in spent fuel is repeatedly recycled overcomes the limitations imposed by the
very finite natural uranium resource and dramatically reduces the volumes and
long-term radiotoxicity of fuel cycle wastes. Generation IV reactors improve
sustainability by creating the opportunity to use high-grade nuclear heat to
displace conventional fossil-fuelled heat sources to supply process heat to a
diverse range of industrial uses. Novel fuel and coolant combinations, such
as those found in molten salt reactors offer the possibility of integrated
recycling of fuel thus closing the fuel cycle within the boundary of a
reactor site.

Clearly, the above benefits will not be obtained easily. At the moment six
basic systems, based on fuel, coolant, and neutron spectrum combinations are
proposed for further development. Each system faces its own challenges with
regard to materials performance, engineering, economics, the requirements of
licensing and safeguards systems, and public acceptability.

This lecture presents the current status of a selection of Generation IV
reactor technologies, explores applications and opportunities for deployment,
including the prospects to have small modular variants, and address their
main challenge

Title: Free-flying fullerenes

Fullerenes were discovered over 30 years ago but continue to throw up
surprises and provide convenient model systems for developing theoretical
techniques and studying the fundamental properties of complex molecules.
The recent laboratory confirmation of the presence of fullerenes in
interstellar space by the Maier group in Basel may have far-reaching
consequences for our understanding of astrochemistry.

In this talk I will briefly review some of the fundamental studies of ther
properties of fullerenes in the gas phase that my group has been involved
with over the years that can help explain how fullerenes survive the harsh
conditions of space. I will also discuss our more recent studies of the
seemingly contradictory nature of fullerenes that can be explored by using
angular-resolved fs photoelectron spectroscopy: the appearance of
thermoelectric electrons (modelled with a two-temperature model more familiar
in condensed matter physics) along with evidence for the excitation of well-
resolved states based on the population of diffuse hydrogenic molecular
orbitals. The study illustrates the interesting position of fullerenes, with
properties bridging the gap between atomic/molecular systems and bulk matter.

Title: Long-period transiting exoplanets and their population

Abstract: The Kepler Mission has discovered thousands of exoplanets and
revolutionized our understanding of their population. This large, homogeneous
catalog of discoveries has enabled rigorous studies of the occurrence rate of
exoplanets and extra-Solar planetary systems as a function of their physical
properties.  Transit surveys like Kepler are most sensitive to planets with
shorter orbital periods than the gas giant planets that dominate the dynamics
of our Solar System. I have developed a fully-automated method of discovering
and characterizing long-period transiting planets with only one or two
transits in the Kepler archival light curves. Since the method involves no
human intervention, I can also precisely measure the completeness function of
the discoveries and place constraints on the occurrence rate of exoplanets
with orbital periods longer than 2 years. I will present this method and the
statistical tools developed as part of this project.

Title: The ADMX search for QCD axions in the Galactic Halo

Abstract: Axions are a sometimes-neglected candidate solution to the dark
matter problem. They don't require any new physics at the electroweak scale,
and their existence would complete the standard model by explaining the
observed conservation of CP in the strong interactions. Detecting axions is
not easy because their couplings to more conventional particles are feeble,
but since 1994 the ADMX experiment has been searching for axions with a very
sensitive and beautiful detector based on an RF frequency cryogenic
electromagnetic resonator and the world's lowest noise AM radio! Sheffield
has collaborated on ADMX since 2007. I will summarise both the experiment in
general, as it approaches the beginning of its new run, and on Sheffield work
to solve the long-standing problem of how an RF resonator can be tuned over a
very large range of resonant frequencies.

Title: Proteins Folding and Failing to Fold: How Good is Nature at Origami

Abstract: Evolution has provided humans with more than 30,000 genes that
encode the sequences of amino acids that make up our repertoire of proteins.
Proteins emerge from the ribosome during their synthesis as linear chains of
amino acids. Folding into a unique three dimensional structure, and avoiding
degradation, is then needed in order for proteins to become functional.
Folding is highly controlled in cells, with a myriad of folding factors,
chaperones and proteases being carefully controlled and tuned so as to
recognise correctly folded proteins from their misfolded counterparts.
Failure of these mechanisms leads to severe human diseases, the majority of
which lack successful therapies. One class of these diseases is amyloidosis,
which includes Alzheimer’s, Parkinson’s and type II diabetes, which are
major threats to health in the developed and developing worlds.

In this lecture I will introduce current concepts and understandings of how
proteins fold and how and why they misfold, garnered from a host of
structural, biophysical and computational methods. How small changes in
protein sequence enhance the probability of nucleated growth of amyloid
fibrils will be discussed, as well as the properties of amyloid fibrils
themselves which act as toxic nanomaterials.

Title: Understanding the clock: physics with pulsars

The canonical picture of pulsars as well behaved clocks is being challenged
by recent observations, that reveal time variability of the radio emission
and the rotational properties of a number of sources. The data point towards
intrinsic, magnetospheric, and propagation related effects. I will review
the technique of pulsar timing, which is providing stringent GR tests and
promise of nHZ GW detections in the future, show the ways in which pulsars
are "misbehaving", and discuss the physics we can address while trying to
"correct" the clocks.

Title: The General Relativistic two body problem: recent results

Gravitational Waves emitted by inspiraling and coalescing compact binary
systems requires for their detection accurate theoretical modeling. In the
early inspiral phase the post-Newtonian (PN) approximation to General
Relativity needs to be pushed to high order for data analysis purposes and
high accuracy comparison with Numerical Relativity computations describing
the final merger and ringdown phases also demand extreme precision. In this
talk an overview of the problem of deriving the equation of motion of
compact binaries will be given, with emphasis on the recent efforts applying
effective field theory techniques within the PN framework, which are also
important for applications to self-force comparisons and effective-one-body
calculations.

Title: Galaxy Formation and Evolution in the JWST Era

Abstract: A comprehensive analysis of star-forming galaxies (SFGs), including a
crucial sub-population of Lyman alpha emitters (LAEs), at high redshifts (z>2)
using multi-wavelength photometry and deep spectroscopy is vital for
understanding the physical processes that govern the star formation activity
and galaxy assembly through cosmic time. Until now, such studies were limited
to small number of galaxies because of the lack of large area, deep observations
at high redshifts.

With extensive multi-wavelength photometry from HST deep fields, and deep
ground-based spectroscopy from ESO/VLT, we can now investigate physical
properties of a large sample of SFGs/LAEs at z~2-6. I will present results from
recent studies based on spectroscopic and photometric data of SFGs/LAEs at high
redshift with a look towards upcoming surveys/missions.

Title: Hubble Frontiers Fields: Some insights after 2 and half years of
       observation

The Hubble Frontier Fields (HFF) initiative constitutes the largest commitment
ever of HST time to the exploration of the distant Universe via gravitational
lensing by massive galaxy clusters. This program devotes 140 orbits of HST
time to deep imaging observations of each of six cluster lenses reaching
m~29 (AB) uniformly from the optical to the near-infrared. These clusters were
chosen for their strong lens properties, and are all highly disturbed objects,
showing major and minor merging on-going processes, making them ideal targets
to trace the Cosmic Web assembly. While combining strong and weak-lensing
regimes to map the total mass with X-rays observations of the hot gas and
spectroscopy of cluster galaxies to look at their direction of motion, we can
thus study the dynamical scenarios in place within these massive galaxy
clusters, and trace the sub-structures engaged. I will present a new
multi-wavelength picture of the first two HFF clusters. The depth of these
dataset makes these clusters amazing Cosmic Telescopes, but also enables us
to get an unprecedented understanding of the cluster physics. I will present
a comparison of the dark matter, light and gas distributions, that will lead
us to the distribution of substructures within the MACSJ0416 , and Abell 2744
vicinities. Finally I will discuss the different clues that these observables
provide on the evolution processes in massive galaxy clusters.

If time permits, I will discuss one of the most beautiful HFF discovery,
SN Refsdal, the first multiply-lensed supernovae discovered by Kelly et al.
(2015) in MACSJ1149 . This particular event is a rare chance to test our mass
modelling techniques, and hopefully improve our methods. I will thus give an
overview of the lensing community's work on SN Refsdal, and discuss the
appearance of its last multiple image.

Title: Random explorations of material structure space

The use of stochastic optimisation strategies for first principles structure
prediction is now well established. There are many examples of these
techniques making genuine discoveries. Ab Initio Random Structure Searching
(AIRSS), in which initial starting structures are randomly generated and
relaxed repeatedly, is extremely simple, reliable and suited to high
throughput computation. Typical functional materials are ternary, or
quaternary compounds. It is important to perform a search over compositional
space as thoroughly and broadly as possible. I will discuss how AIRSS may be
used to do this, paying particular attention to pulling apart structures we
have already found, to make new, random ones.

Title: Tidal disruptions of stars by supermassive black holes: dynamics, light
       and relics

Most supermassive black holes in the local universe lie dormant, with only one
in a hundred accreting at their Eddington limits.  Aside from this active
minority, and the black holes in nearby galaxies that we can observe to
influence the dynamics of stars and gas, most remain difficult to study. Tidal
disruptions of stars by supermassive black holes give these dormant black
holes a chance to be seen once every ~10,000 years, and each tidal disruption
brings along with it a host of observable signatures that can be studied from
gigaparsecs away, from the moment of the disruption to millennia after a
disruption has occurred. In my talk I will present work I have done on tidal
disruptions of stars, and describe their dynamics, observational signatures
from real-time monitoring, and relics of disruption that may exist in plain
sight.

Title: Rotation, Magnetic Activity and Mass Loss of Sun-Like Stars

An enormous amount of what we know about the universe and our own place on
Earth depends on our understanding of stars. Yet, even for the most familiar
stars, there are still major unsolved questions related to rotation, magnetic
activity, and mass loss. I will discuss an emerging self-consistent picture
that links all of these processes together and to the overall evolution of
Sun-like and low-mass stars. This progress is due to large and diverse new
datasets, advances in physical models for the loss of angular momentum (which
itself depends upon magnetism and mass loss), and the incorporation of these
models into long-term stellar evolution calculations.

Title: The Space Weather of other Suns

Abstract: "Space Weather" describes the impact that the Sun has on its
environment through the magnetically powered flares, mass ejections and wind
that it produces. Although the Sun is a relatively inactive star, the impact
of a large solar mass ejection can damage satellite electronics, shut down
terrestrial power grids and disrupt radio communications. On more active
stars, we might expect even more dramatic space weather and a greater impact
on any orbiting planets. In this talk I will describe how we can use
observations that reveal the geometry of stellar magnetic fields to
understand the nature of the accompanying space weather.

Speaker: Daisuke Kawata, UCL

Title: Structure and Metallicity Distributions of Chemically Decomposed
Thick and Thin Disk Populations of the Milky Way Disk

We first summarise the thick and thin disk formation scenario commonly seen
in cosmological N-body simulations. As suggested in Brook et al. (2004), a
hierarchical clustering scenario causes multiple minor gas-rich mergers, and
leads to the formation of kinematically hot disk, thick disk population, at
a high redshift. Once the mergers become less significant at later epoch,
the thin disk population starts building up. Because in this scenario the
thick disk population forms intensively at high redshift through multiple
gas-rich mergers, the thick disk population is compact and has
systematically higher [α/Fe] abundance than the thin disk population. In
addition, we show that the current cosmological simulation also naturally
predict that the thin disk population is flaring at the outer region.
Consequently, at the high vertical height from the disk plane, the compact
thick disk population (low metallicity and high [α/Fe]) is dominant in the
inner region and the flaring thin disk population (high metallicity and low
[α/Fe]) contributes more in the outer region. This helps to explain the
positive radial metallicity gradient and negative radial [α/Fe] gradient
observed at the high vertical height in the Milky Way stellar disk.

We then discuss how radial migration impacts the metallicity distribution of
the thin disc population. We demonstrate that the flaring star forming
region could be required to explain the negative vertical metallicity
gradient observed in the thin disc population.

Speaker: Prof Stephen Smartt, Queens University, Belfast

Title: Collapse of massive stars to black holes - the missing progenitors of
supernovae
Massive stars collapse to form neutron stars and black holes. In doing so
they produce the population of core-collapse supernovae we see in the nearby
Universe.  Over the last 15 years we have been able to directly identify
the progenitors of supernovae, link them with explosions and in some cases
confirm the disappearance of the star. The number of discoveries of
progenitors now allows some interesting comparisons between observational
data and explosion models.  There appears to be a distinct lack of bright
supernovae from the most massive stars, which suggests that stars over a
certain mass limit produce black holes with no visible explosion.

I will discuss this mass limit, which could be as low as 16 solar masses and
the implications in the LIGO/Virgo era of detections of compact binary
mergers.

Title: Solar activity, stellar rotation and anomalous weakened magnetic
braking

Abstract: The rotation of Sun-like stars plays a key role in the generation
of magnetic fields by dynamo action. These magnetic fields act as a brake on
the rotation, so that Sun-like stars spins down over their lifetimes. Or so
we thought. Using 4 years of observations from NASA's Kepler space
telescope we have discovered that stars that are more evolved than the Sun
stop spinning down. The most likely cause of this reduced magnetic braking
is that a significant change in the strength or topology of magnetic field
occurs at around the age of the Sun. This has huge implications for our
understanding of the dynamical evolution of Sun-like stars, and suggests
that the Sun may be approaching a significant change in behaviour in the
not-too-distant future (in stellar evolutionary terms!).

TITLE: A NEW PARADIGM TO BLACK-HOLE SPIN PRECESSION

The dynamics of precessing black-hole binaries in the post-Newtonian regime
is deeply characterized by a timescale hierarchy: the orbital timescale is
very short compared to the spin- precession timescale which, in turn, is
much shorter than the radiation-reaction timescale on which the orbit is
shrinking due to gravitational-wave emission. The binary dynamics is
typically studied in an orbit-averaged fashion: one only cares about the
orbit itself, not the instantaneous position of each black hole. Here we
also average over the precessional time, thus considering the precessional
cones "as a whole", without tracking the spin's secular motion. These
solutions improve our understanding of spin precession in much the same way
that the conical sections for Keplerian orbits provide additional insights
beyond Newton's 1/r^2 law. Double averaging leads to impressive
computational speed-up: post-Newtonian inspirals can now be computed from
arbitrarily large separations, thus bridging the gap between astrophysics
and numerical relativity. We also present the discovery of a new dynamical
instability in binary black holes with aligned spins. The onset of the
instability lies in the sensitivity windows of future detectors LIGO /Virgo
and eLISA, thus predicting binaries that start precessing while being
observed. More on arXiv 1411.0674 and 1506.09116 (PRL).

Asteroseismology and Exoplanets: Listening to the Stars and Searching for New Worlds

IVth Azores International Advanced School in Space Sciences

17-27 July 2016, Horta, Faial, Azores Islands, Portugal
Website: [www.iastro.pta] Tiago Campante (Chair)

This International Summer School will cover two scientific topics that share many
synergies and resources: Asteroseismology and Exoplanetary Science. Therefore, the
proposed program aims at building opportunities for cooperation and sharing of methods
that will benefit both communities. The School will include both a teaching and a
hands-on components, while bringing together a group of young and dynamic lecturers who
have already established themselves as leaders in their respective fields of research.
It is mainly aimed at PhD and MSc students (although postdocs are also encouraged to
apply) in any field of Astrophysics. Students will also be given the opportunity to
present their own research work by bringing a poster to the School.

The School will take place in the town of Horta, located in the island of Faial. Faial
is one of the nine islands that make up the beautiful archipelago of the Azores,
situated in the North Atlantic Ocean about 1,360 km (850 mi) west of mainland Portugal.
The Azores are served by frequent flights from Europe and the US/Canada.

There is an upper limit of 40 attendees to the School. Due to the large number of
expected applications, a pre-registration process will be in place that requires
applicants to submit a short CV (max. 2 pages) and a motivational letter (max. 1 page).
Pre-registration should be done through the School's website and will close on 18 March
2016. Information on the registration fee is available on the School's website.

Title: Molecular Electronic Materials and their application to Photovoltaics

Abstract: The application of molecular and hybrid semiconductor materials to
optoelectronics presents both an opportunity, in terms of the vast range of
material properties and applications that can be achieved through chemical
synthesis, and a challenge, in relating optoelectronic properties of the
resulting devices to the chemical structure and microstructure of the
materials. The challenge is complicated by the intrinsic disorder in
electronic energy levels, the structural heterogeneity of organic
semiconductors and their dielectric properties. In this seminar, we focus on
the application of these materials to photovoltaic energy conversion, where
the prospect of low-cost solar panel manufacture using printing or coating
has attracted intense interest. We discuss how the molecular nature of the
materials influences the processes of light harvesting and photocurrent
generation in a solar cell. We show how a range of electronic, spectroscopic
and structural measurement techniques, together with molecular and device
modelling, can be used to relate the properties of the materials to their
performance in solar cells. Finally we address the factors that limit power
conversion efficiency in such devices.

Title: Planetary Systems through all Stages of Stellar Evolution

Abstract: We know that planetary systems around white dwarfs are just as
common as those around main sequence stars. However, observations reveal
significant gaps in our understanding about how planets, asteroids, comets
and pebbles undergo physical and orbital changes as their parent stars
evolve off of the main sequence. We have performed full-lifetime (14 Gyr)
numerical simulations of multi-planet systems across all phases of stellar
evolution, incorporating realistic profiles for stellar mass loss and
stellar radius variability, and including test particles and wide binary
stellar companions. We demonstrate that closely-packed planetary systems can
remain stable throughout the main sequence and for many Gyr during the white
dwarf phase before unpacking and triggering scattering events. These events
may generate an ever-changing dynamical architecture around the white
dwarfs, and perturb planets onto orbits which can be detectable by transit
photometry.

of fields in the ecliptic plane in ~80 day photometric campaigns. This has
enabled a dramatic extension of the exoplanetary science and
asteroseismology of Kepler to a number of nearby clusters and standard
stars. With only two reaction wheels, K2 suffers from severe systematics
introduced by its regular pointing corrections. In this talk, I will
describe the Oxford pipeline for K2 systematics correction, using Gaussian
Processes to non-parametrically model photometric errors as a function of
pointing inputs, and will discuss the planet candidates we obtain with this
approach. I will also present the first results of the Kepler/K2 Saturated
Stars Survey (K2S3), where we extract light curves of the brightest stars in
Kepler and K2 from previously-unused calibration data or from their
scattered-light halo.

Many of these stars were not conventionally targeted due to their severe
saturation, and due to their position on the ecliptic, the K2S3 sample is
directly complementary to the targets selected for the upcoming Transiting
Exoplanet Survey Satellite. We have been able to study the asteroseismology
these sources, including RR Lyr and the Pleiades, and search for planets
around some of the nearest stars to the Sun.

Title: The EAGLE Project: Numerical modelling of the 'Evolution and Assembly
of GaLaxies and their Environments'

I will briefly recap the motivation for, and progress towards, numerical
modelling of the formation and evolution of the galaxy population – from
cosmological initial conditions at early epochs through to the present day.
I will introduce the EAGLE project (Schaye et al. 2015; Crain et al. 2015),
a flagship program of such simulations recently conducted by the Virgo
Consortium. These simulations represent a major development in the
discipline, since they are the first to reproduce the key properties of the
evolving galaxy population, and do so using energetically-feasible feedback
mechanisms. I shall present a broad range of results from the first batch of
EAGLE papers, concerning the evolution of galaxy (and black hole) masses,
their luminosities and colours, their atomic and molecular gas content, and
the structure of their host (dark matter + hot gas) haloes. Besides
exploring these interesting astrophysical outcomes, I hope to convey some of
the strengths and limitations of the current generation of numerical models.

Title: A Binary View of Massive Stars

The Universe we observe today has been shaped extensively by massive stars.
From birth to death and throughout their entire lives, they mold their near
and far environment in multiple ways, by driving galactic dynamics, and
chemically enriching the interstellar environment through their explosive
deaths. In spite of their obvious importance, observational challenges have
severely limited our knowledge of massive stars. In particular, their great
distances and scarce numbers induce observational challenges to our
understanding of their formation and evolution. However, we do know that
massive stars love company. I will present an overview current picture of
the multiplicity properties of massive stars and discuss the implications on
their formation.

Title: The KMOS Redshift One Spectroscopic Survey (KROSS): The resolved
Dynamics, Star- Formation and Chemical Properties of 1000 z~1 star forming galaxies

I will present the first results of KROSS, a major UK-led KMOS GTO survey to
observe the redshifted H-alpha emission in ~1000 star-forming galaxies at
z=0.8-1.5. Selecting galaxies from the star-forming "main-sequence" (stellar
masses 1e9.5-1e11.5 Msol and SFR 1-30 Msol/yr), KROSS will measure the
resolved dynamics, chemistry and star formation in a statistical sample of
galaxies in to address:
 (i)  How does the fraction of disks evolve as a function of z and environment?
(ii)  Are major (and minor) mergers more prevalent at high-z ?
(iii) How does the relation between the star-formation, stellar mass and dark halo evolve with z and environment?
(iv)  How does the angular momentum of galaxy disks evolve with z, stellar
mass and environment;
(v)   Are chemical abundance gradients of early disks stronger or weaker than local spirals?
These are critical issues for developing models of galaxy formation, in
particular to determine if stellar mass assembly is dominated by secular
isolation or via merger-induced growth. In this talk I will show the first
500+ galaxies from the sample, which already constitutes the largest ever
resolved H-alpha survey at this redshift.

Abstract:

Pulsars can be employed as precision timing tools due to the unwavering
nature of their radio emission and of their rotation; it is hoped that
precise pulsar timing measurements will soon permit the direct detection of
gravitational waves. In recent years, however, we have started to see that
unmodelled variability in some pulsars occurs over a broad range of
timescales, both in their emission and in their rotation. This is, of
course, detrimental to the pulsar's utility as a precision timing tool, and
presents a problem when looking for the faint effects of a passing
gravitational wave. I have analysed the variability of various pulsars using
new techniques and will present the results.

Title: Statistical detection of halos in galaxy clusters

Abstract

Statistical detection of halos in galaxy surveys
I will discuss recent work to present a novel Bayesian methodology for
detecting halos of different masses in galaxy survey observations, whilst
jointly quantifying the corresponding uncertainties. This methodology first
uses the previously published HADES algorithm to create an ensemble of
realisations of the matter density field throughout the survey volume. Using
an N-body simulation to relate the density field to halo mass, we then use a
Bayesian chain rule to build up maps of the detection probability of halos
about specific mass thresholds. Demonstration of the methodology using a
realistic galaxy mock catalogue shows an excellent agreement between the
peaks in the probability maps and the positions of the dark matter halos. We
conclude that this method is a promising novel tool for analysing
observations of the large-scale cosmic web.

Title: Black Holes in Globular Clusters

Abstract

I'll review searches for black holes (both stellar and intermediate-mass—the
latter meaning 100s-1000s of Msun) in globular clusters. Searches for
intermediate-mass black holes in globular clusters have not found convincing
evidence, despite tantalizing hints. Bright X-ray binaries in extragalactic
globular clusters do provide evidence favouring the existence of black holes
in globular clusters. Recently, new discoveries of radio-bright X-ray sources
in Galactic globular clusters are providing evidence for a population of low-
accretion-rate black hole systems with surprising properties.

Title: Shining a light on black holes

When black holes collide, their enormous gravitational forces create
ripples in the fabric of space and time. Although Einstein predicted
the existence of these gravitational waves, he was certain that they
could never be detected.

Advances in technology, from lasers to modern quantum optics, have
fundamentally changed the way we design precision instruments.
Measuring a gravitational wave is now a possibility, while remaining one
of the greatest challenges in experimental physics. The task is to
detect tiny changes in the distance between two objects, a change that
is 100,000 times smaller than the core of an atom. Over several decades
a new type of laser interferometer has been developed, and several
kilometre long gravitational wave detectors have been constructed around
the world.

Now, almost exactly a hundred years after Einstein's predictions, two
detectors are beginning to operate with high enough sensitivity to make
the first detection of a gravitational wave, exceeding Einstein's
imagination. Professor Freise will talk about an extraordinary journey
in experimental physics and the invention of new laser instruments to
look into the skies and listen for the echoes of black holes and dying
stars.

Title: Use of binary radio pulsars with ultra-compact companions to
understand basic physics

Binary radio pulsars with other neutron stars or black holes as companions
can serve as excellent laboratories to test various aspects of basic
physics. In this talk, I will first try to seek an answer to the puzzle of
non-discovery of any neutron star-black hole binary so far. Then, I will
discuss potential problems we might face while timing such pulsars after
the discovery is made. The problem can arise mostly due to the spin-orbit
coupling effect from the spin of the black hole. I will also explore
whether such a neutron star-black hole binary is really superior to
falsify general relativity and establish alternative theories of gravity.
Finally, I will briefly discuss how careful study of radio pulsars in
of radio pulsars in neutron star-neutron star binaries can help to
constrain the dense matter equation of state.

Title: Nested Sampling

Nested sampling provides an alternative to traditional MCMC sampling
methods. MultiNest is a generic Bayesian inference tool that uses nested
sampling to calculates the evidence, with an associated error estimate,
and produces posterior samples from distributions that may contain
multiple modes and pronounced (curving) degeneracies in high dimensions.
This algorithm significantly outperforms existing MCMC techniques in a
wide range of astrophysical inference problems. I will discuss the
principles of nested sampling and describe the MultiNest algorithm and
its application to toy examples and a cosmological inference problem.
The MultiNest software, which is fully parallelized using MPI and
includes an interface to COSMOMC, is available at
http://www.mrao.cam.ac.uk/software/multinest/ [www.mrao.cam.ac.uk]

Michael is a theoretical astrophysicist with research interests in
Anisotropy of the cosmic microwave background. Bayesian analysis
techniques. Star-formation in molecular clouds. Radiative transfer.

For the hands-on session we will be using Multinest which can be
download for free: here

Multinest is available in various interfaces, We recommend that you
install any interface of multi nest well in advance of the session (it
requires pre-registration and approval) so that if you have any problems
you can email me. There will not be time during the session to install
multinest.

Speaker: Dr Simon Vaughan, University of Leicester

Title: Variability as a tool to study accreting black holes and neutron
stars

The fluctuating brightness of cosmic X-ray sources, particularly
accreting black holes and neutron star systems, has enabled enormous
progress in understanding the physics of turbulent accretion flows, the
behaviour of matter on the surfaces of neutron stars and improving the
evidence for black holes. Most of this progress has been made by
analysing and modelling time series data in terms of their power- and
cross-spectra.

In this talk I am going to concentrate on a related but often overlooked
aspect of their variability: the rms-flux relation. I will illustrate
the basic idea and its consequences using examples of X-ray variability
from X-ray binaries, Ultra-luminous X-ray sources (ULXs) in nearby
galaxies, and AGN , including Kepler optical monitoring of a Blazar.

Speaker: David Van Dyk, Imperial College London

Title: The Unified Statistical Analysis of Populations of Sources:
Advantages of "Shrinkage Estimates" in Astronomy

Astronomical studies often involve samples or populations of sources. The
parameters describing the sources can either be fit to each source in a
separate analysis, or all be fit in a single unified analysis. The latter
strategy allows us to incorporate the population distribution into a
coherent statistical model and exhibits distinct statistical advantages.
In particular, objects with smaller error bars and well-constrained
parameters allow us to estimate the population distribution, which in turn
can be used to better estimate the weakly-constrained parameters
associated with objects with larger error bars.

The fitted values of such weakly-constrained parameters will "shrink
towards" the population mean, and are thus called "shrinkage estimates".
This talk describes both frequentist and Bayesian advantages of shrinkage
estimates and illustrates how they can be used in astronomy. In the first
of two examples we estimate the absolute magnitudes of a SDSS sample of
288 Type Ia Supernovae using shrinkage estimates and illustrate how they
differ from naive estimates.  In the second example, we use photometric
magnitudes of a sample of galactic halo white dwarfs to simultaneously
obtain shrinkage estimates of the stellar ages and an estimate the age of
the halo.

Title: Scalable Bayesian Inference.

Problems at the frontiers of applied statistics, from physics to ecology
to epidemiology and pharmacology, require not only large data sets but
also the complex statistical models needed to describe the intricacies of
the data. Drawing inferences from these problems necessitates both
scalable and general statistical algorithms and their computationally
efficient yet user-friend implementations. Stan is a user-focused platform
for Bayesian inference that wraps the state-of-the-art Hamiltonian Monte
Carlo sampler with an expressive modeling language that makes it easy to
build and learn from complex models. In this talk I'll review the basics
of Hamiltonian Monte Carlo and Stan before presenting a series of
interactive examples for the audience.

Michael is a significant contributor to the widely used Hamiltonian Monte
Carlo code STAN.

All are welcome and refreshments will be provided.

The detection of gravitational-wave signals is still one of the most
challenging areas of experimental physics. And the reward for success will
be considerable in that the information carried by these signals will give
us new insight into the hearts of some of the most violent events in the
Cosmos—from the formation of black holes to aspects of the evolution of the
Universe. A global network of gravitational-wave detectors is now reaching
the final stages of construction, with first data expected in 2015. The
nature of gravitational waves, how the detectors work, and what the data
from the detectors can tell us about the Universe we inhabit, will be
discussed.

Title: ALMA surveys of high-redshift, star-forming galaxies

I will present some recent results from ALMA cycle 0/1 surveys of distant,
sub-mm galaxies (SMGs). The ALMA data allow us to investigate the properties
of SMGs (redshift distribution, star formation rates, stellar masses and AGN
activity). I will show that these distant (z = 2.5) Ultra-luminous Infrared
Galaxies have star-formation rates of 300-1000 Msol/yr, substantial stellar
masses (M* = 6E10 Msol) and cold molecular gas fractions of 40% - which are
many of the properties expected for the progenitors of today massive spheroids
and elliptical galaxies. Indeed, accounting for the fading of the stellar
populations, I will show that the space density of the descendent of SMGs are
consistent with the entire population of local luminous ellipticals. Finally,
I will show some recent results from ALMA cycle 1 where we have obtained
higher resolution (0.3arcsec) maps of a sub-sample of bright SMGs.

Speaker: Jim Geach, University of Hertfordshire

Title: Galaxy-scale feedback in massive galaxies without AGN

In traditional models of galaxy evolution, feedback associated with an
active galactic nucleus (AGN) have been invoked as the standard channel to
regulate stellar mass growth at the massive end of the mass function. We
have been investigating a sample of massive, compact galaxies that exhibit
ultra-fast gas outflows (up to 2500 km/s) with no evidence of significant
AGN activity.

Recently we have shown that in at least one of these galaxies, a significant
amount of molecular gas is being driven out at speeds of up to 1000 km/s. I
will discuss how this sample demonstrates that stellar feedback can be an
effective channel for curtailing stellar mass growth in massive galaxies,
and in particular the role of stellar radiation pressure as a mechanism for
launching galaxy scale super winds from high density star forming regions.

Message from Trevor Ponman

Postcard from Cornwall With apologies for the two month delay, I would like to thank everyone who signed my farewell card, or contributed to the collection. I didn't know about the latter, since Alberto was planning to surprise me with a present from the proceeds, before deciding (wisely) that this was not the best idea. We've been down in deepest Cornwall (near Penzance) for 6 weeks now and, having inherited a nice but overgrown garden, my plan is to buy a rather special tree (species still TBD) and some other plants to remind me of your generosity. The pace of life is different down here, which is one of the attractions, but we are progressively turning the house from a warehouse full of boxes into a home, and I think we will be happy. For those of you who have never seen Mounts Bay, I can recommend it as one of the most beautiful places in the country to watch the sun set. I'll continue to visit every few weeks for at least the next year or so, and so will bump into many of you from time to time. All the very best for the future. Trevor

Speaker: Nial Tanvir, University of Leicester

Title: Merging neutron stars, gravitational waves and the origin of the
heavy chemical elements

Mergers of compact binaries involving neutron stars lie at the intersection
of several key problems in astrophysics. They are widely thought to lead to
short-duration gamma-ray bursts; to be an important production site for the
nucleosynthesis of r-process heavy elements; and to emit strong
gravitational wave (GW) signals that are the most promising for detection by
the next "advanced" generation of detectors. Recently, the first evidence
for kilonova emission, predicted to be produced by the radioactive decay of
species created during such a merger, was found, associated with sGRB
130603B. I will review this discovery together with other observational
constraints on the nature of sGRBs, and consider the prospects for kilonovae
as electromagnetic signatures of GW events.

Following up on some discussions within the gravitational-wave group, I'd
like to offer a Q&A session on "anything * you wanted to know about the
astrophysics of gravitational-wave sources but were afraid to ask" at noon
on November 19. This is very much meant to be open to all of ASR and HiROS,
so please come along if the topic interests you, even if this is not
something you normally work on.

Although I am certainly open to questions on the spot, I would be very
grateful if you could e-mail me your questions in advance so I could plan a
more coherent discussion around the topics of interest. Andreas kindly
agreed to serve as moderator, so he will keep me from veering off topic too
much. I Mandel
* For this session, let's focus on the astrophysics of LIGO sources.

If the format works, we can have additional sessions on low-frequency
sources, data analysis, and detectors, and perhaps other topics if people
find these useful.

Title: Cosmological Measurements from Galaxy Clustering

that encode this information in the observed clustering of galaxies, and
present recent results from the Baryon Oscillation Spectroscopic Survey (BOSS).
I will then look ahead to future surveys including the Dark Energy Spectroscopic
Instrument (DESI) and the ESA Euclid satellite mission, showing how they will
revolutionise our understanding of cosmic acceleration.

Monday 27th October 2014, 12pm, Physics West 106

Speaker: Dr Guy Davies, University of Birmingham

Title: Stellar seismology: The solar-stellar connection

The study of stellar structure and evolution provides one of the fundamental
building blocks of astrophysics and some of the most powerful observational
constraints on these theories are provided by helio and asteroseismology.
Inevitably, the well characterised Sun is an anchor and calibrator to any
theory of stellar evolution. The Sun drives our understanding of the stars,
and it is sensible to ask what the stars can tell us about the Sun. Here,
asteroseismology with the Kepler Space Telescope is providing precise
characterisation of individual stars and ensembles of stars. In addition to
characterising interesting systems, such as exoplanet hosts, asteroseismic
results may allow significant progress on the “grand problems” of solar
physics, particularly related to understanding the solar 22-year magnetic
cycle.

In this talk I will review the current status of the Sun-as-a-star. We will
see that questions remain about the rotation of the deep solar interior, the
changing of the solar magnetic field, and the understanding of the solar
dynamo and space weather. I will show how we can precisely characterise
other Sun-like stars and how we are pushing the boundaries of our
understanding by considering ensembles of stars. I will finish by
speculating how the field of stellar seismology will change with the advent
of the SONG, BiSON Mini, TESS and PLATO observatories.

Title: Asteroseismology, the new Keplerian Revolution

In 1926 in the opening paragraph of his now-classic book, The Internal
Constitution of the Stars, Sir Arthur Eddington lamented, “What appliance
can pierce through the outer layers of a star and test the conditions
within?” While he considered theory to be the proper answer to that
question, there is now an observational answer: asteroseismology.

We are in a time of a significant advance in our understanding of stellar
astrophysics with data from the Kepler Mission.  From its rich 4-year data
set nearly 4000 exoplanet candidates have been discovered – the majority of
all known. Kepler has also improved our ability to see pulsations and
x variability in stars by 100 to 1000 times compared
with ground-based telescopes, allowing us to probe stars using
asteroseismology. We are seeing as never before: heartbeat stars, novel
eclipsing stars, spots, flares and magnetic cycles as in our own Sun.
Astrophysics that used to be theoretical is now also observational:

internal stellar rotation from core to surface; gravitational lensing in
eclipsing binary stars; Doppler boosting; multiple pulsation axes; period
doubling; tidal excitation in highly eccentric binary stars.

Kepler data for solar-like stars are now comparable to data for the Sun seen
as a star, giving us masses, radii and ages for hundreds of single stars,
allowing determination of their orbiting planets’ sizes, and giving new
constraints on stellar evolution theory. It is now even possible to see into
the cores of red giants and observe which stars are hydrogen shell-burning
and which also are helium-core burning. This talk will introduce the
concepts of asteroseismology and show a selection of exciting observational
results from the Kepler mission (with emphasis on work that has not been
done at Birmingham!).

Title: Exoplanets - The quest for other worlds

The first exoplanet orbiting a main sequence star was discovered in 1995.
Twenty years later, more than a thousand other planets have been found and
statistical patterns regarding their properties are starting to emerge.
Remarkably, we have been able to probe the atmospheres of several of these
exoplanets, which provide insights about their chemical composition and
climate patterns. Within the coming 3 years, one ESA space mission
dedicated to exoplanets will be launched and two ambitious UK-led
ground-based instruments will be installed. The future of exoplanet science
in the UK has never been so encouraging. I will start by discussing recent
results in exoplanet science. Iwill then detail the synergies between the
future instruments/facilities and show how they fit in an international
framework. I will finally discuss the next pathways to answer one of the
most fascinating questions in astronomy: "are we alone?"

Title: The era of precision stellar astrophysics

Observational stellar astronomy has been revolutionized in the last few
years with the development of large-scale spectroscopic and photometric
surveys and the generalization of techniques such as asteroseismology
hitherto restricted to very limited numbers of stars. This revolution has
not been accompanied with comparable efforts in the development of stellar
models. Fundamental questions, even for the best studied star, remain
unanswered.

In this context I will present some examples, from the Sun to stellar
populations, that show recent successes and limitations of the current
generation of stellar models and will conclude with a personal perspective
of the way ahead.

Title: In the Deep, Dark Lyman-alpha Forest: Exploring Dark Energy and Galaxy
       Formation using the Intergalactic Medium

I will discuss probes of the intergalactic medium measuring both the largest
and smallest scale effects in the extragalactic universe. The Lyman-alpha
forest along the line-of-sight to background quasars is measured providing a
new kind of survey. The BOSS survey (as part of SDSS-III) has probed more
than 60,000 Gigaparsecs in path length and is still growing. We have made the
first measurements of baryon acoustic oscillations on 150 Megaparsec scales
to probe the expansion of the universe, and have seen evidence of clumping in
regions around galaxies on 3 0 parsec scales. I will discuss the future of

Michaela Nelson has been awarded a grant of £1594 from the Royal Society to
do a project with year 6 pupils at Perryfields Primary School. The project
will look at electromagnetism and power generation and will hopefully finish
with a Small wind turbine sited in a partic ularly windy part of the
school grounds.

The final of the IOP's 3 minute wonder competition is taking place on 15th May.
I was a runner up in the regional heats back in November and I was under the
impression that only the winners went through to the finals but I've been
informed that the runners up also get a plac e in the final so I'll be
in London on the 15th talking about dark energy and gravity.

Title: What satellite galaxy evolution tells us about the baryon cycle of
galaxies

Abstract:

The inefficiency of galaxy formation in a cosmological context remains an
unexplained mystery.  There is little doubt that it is a consequence of
the evolution in gas accretion rates, together with energetic "feedback"
phenomena like stellar winds, supernova explosions, and supermassive
black hole-powered accretion. Despite the central importance of this gas
physics, most observational constraints are indirect, and we rely on
comparison with "kitchen-sink" models to tell us whether or not our
understanding of galaxy evolution is on the right track.  One place where
this comparison repeatedly fails is the prediction of the properties of
"satellite" galaxies, and this failure may be indicative of a fundamental
flaw in our understanding of how baryons cycle in and out of galaxies.  I
will present a review of this problem and show what we have learned from
our new results on galaxy groups and clusters at z~1.

Title: Hunting down noises in gravitational-wave detectors

Abstract: Laser interferometric gravitational-wave (GW) detectors are
among the most sensitive instruments that humans have ever built, in
order to measure tiny ripples of spacetime generated by distant yet
energetic astrophysical objects. Achieving the desired sensitivity is not
just a legend about implementing the state-of-the-art technology, but
more about strenuous efforts in understanding and hunting down noises of
both classical and quantum origins. In this talk, I shall give you a tour
of major noises in GW detectors, and remark on some attempts by my
colleagues and me in reducing them. Close to the end of the talk, I will
also mention one interesting spin off the use of quantum-limited GW
detectors as probes for quantum behaviours of macroscopic objects, which
provides us a unique opportunity to test quantum mechanics in a totally
new regime.

Title: Baryonic and modified gravity effects on cosmic structure
formation

Abstract:

Cosmological surveys are based on luminous objects, while cosmological
models most easily predict the statistics of the dark matter
distribution. Hydrodynamical simulations of cosmic structure formation
are the tool of choice for connecting these two realms.

I will present simulation studies of many of those quantities and
relations that are most relevant in this context, including the effects
of AGN feedback on galaxy cluster scaling relations and the matter power
spectrum, which have direct implications for upcoming X-ray and weak
lensing surveys. I will also discuss numerical predictions of the
Lyman-alpha forest, their uncertainties and how they can be used to
constrain cosmology. For the first time we perform such cosmological
hydrodynamical simulations not only within the framework of standard
general relativity theory, but also for screened modified gravity models
which pose a viable alternative to dark energy

Title: How to Build a Big Galaxy

Abstract

The most massive galaxies in the universe are rare, but because of this,
their formation history imposes some of the strongest constraints on our
models of galaxy formation.  In the local universe, massive galaxies like
M87 appear relatively dull, with elliptical morphologies, old stars, and
little ongoing star formation.  For decades, archeological studies
predicted that most of the action during these galaxies' formation must
have occurred at much higher redshift (z > 2).  With the first deep and
wide field surveys of the near infrared sky coming online, we can now
directly observe the progenitors of local massive galaxies as they are
forming.

I will show state-of-the-art observations of this process up to z ~ 4,
where we are finding that the early stages of massive galaxy formation
are in fact extremely dynamic, with huge bursts of dust-obscured star
formation, ubiquitous AGN activity, and significant structural
transformations.  I will also discuss what we expect to learn up to z ~
6-7 in the coming years from ongoing deep/wide surveys such as
UltraVISTA, and what we expect to learn in the JWST era, when we may be
able to observe the process of massive galaxy formation right out to its
initial stages at z ~ 10-20.

Title: Squeezed light: using quantum optics to develop the gravitational wave
detectors of the future

We are rapidly approaching a new era in the decades-long world-wide effort to
directly detect gravitational waves. The first arm lock of both Advanced LIGO
interferometers has just been achieved, and in a few years' time the promise
of delivering detectors with unprecedented strain sensitivity will be realized,
thus opening the door to routine signal detection.  We are already planning
upgrades to the advanced detectors with the understanding that achieving, let
alone surpassing, the design sensitivity is a challenging task. I will present
one such challenge, that of reducing the noise in the frequency band limited by
photon shot noise, a region that brings us just within reach of the exciting
potential to constrain the neutron star equation of state. While the standard
approach to further improve strain sensitivity at these frequencies is to
increase laser power, an alternative is to manipulate the quantum state of the
field in the interferometer. Through the integration of a squeezed vacuum
source at the German-British laser interferometer, GEO 600, we are forging this
path forward. I will present the latest developments of squeezed vacuum control
and how squeezing will affect the future of gravitational wave detectors.

Annual fire systems testing and essential maintenance on electrical infrastructure

Tuesday 17 December 2013

In order to maintain insurance cover for the University's data centres we
are required to carry out a series of tests each year on our fire
detection and suppression systems. The process this year is being
modified to allow us additionally to repair a significant fault on the
Data Centre electrical systems. To minimise the risk of disruption for
University staff, students and visitors, key services will be migrated to
our secondary Data Centre and will remain operational for the duration of
the work, using resilience mechanisms being delivered by the Resilience
Project. Migration periods for key services will be 12-2pm and 7-9pm, on
17 December (note that during migration, individual services will be
subjected to short periods of disruption).

These key services include:

Teaching and Learning Services such as Timetabling, Library Catalogue and
access to online journals

Web Services such as the University website, intranet, and Staff and
Student Portals

Finance Systems (e.g. Payroll, Proactis and Coda)

Admin systems such as Pure, Data Warehouse, Document Management, Business
Intelligence and Student Records (Banner & BIRMS)

Other essential tools such as Email and Filestore

As well as the supporting infrastructure for these services e.g. the
network, virtual servers and storage on which they rely

It should be noted that other services will be at some risk throughout
the testing period.

Birmingham Heroes Lecture: Music of the Stars

Thursday 17th October, 6:15-8:30pm, Physics West 117

When you look up at the sky on a clear night to do ever ask yourself: how
many of the twinkling stars have planets, like the planets orbiting our
own sun?  And how many of those planets might be capable of harbouring
life, like the precious planet we live on?  Is there some special
combination of properties that a star must possess to elevate the chances
of it hosting a habitable planet? Or are some sun-like stars just too
unsafe for their planets?

In this second Birmingham Heroes lecture, Professor Bill Chaplin will
discuss the leading role that Birmingham is playing in the study of other
stellar systems in our galaxy. The lecture will be held in Birmingham and
will see Professor Chaplin reprise his `Music of the Stars' lecture given
at the Institute of Physics in May 2013.

Observatory Open Afternoon

Friday 27 September 2013, 1400 - 1800 Hours

You are warmly invited to visit the University of Birmingham Observatory
at Wast Hills Friday afternoon, 27th September 2013. A small team of us
will be at the Observatory from 2pm-6pm (and later if sky is clear) to
show, and demonstrate our new telescope (a 0.5m diameter Ritchey
Chretien), and supporting control systems.
We are still in the process of commissioning the telescope, with several
important unfinished tasks, dangling cables, etc.. So this will be an
informal event for colleagues and friends, very much an "open house",
"take us as you find us", style.

That said, we had "first light" with the new telescope last week - a very
exciting and important landmark! So you will be able to see the telescope
in action. If the sky is clear, you're welcome to stay into the evening
while we do some observing.

The Observatory can accommodate a limited number of people. So it will be
very useful to get an idea of how many people are likely to visit. This
will help us firm up plans next week, including steps to smooth out
visitor numbers through the afternoon if some times prove more popular
than others.

Please email your reply to Jo Cox j.s.cox@bham.ac.uk if you intend to
come, and/or would like more information. Please reply ASAP. We will
start reviewing replies on Monday afternoon and will firm up plans on
Wednesday afternoon.

Please also contact Jo for directions to the Observatory. There is space
for some cars to park at the Observatory and in a nearby layby, however
please try to car share where possible.

I'm happy to answer questions via email, or in person at School Committee
meeting.

Excellence in Doctoral Supervision Award

Andreas Freise was awarded the "Excellence in Doctoral Supervision Award"
University of Birmingham Engineering and Physical Sciences, and Alberto
Vecchio was a runner-up for the award. The nomination process not only
involves letters of recommendation from current students, but past
students and the chair of the department as well. This is a highly
competitive award in the University, as both the nominee and the
nominator receive a £1,000 prize. 

These recognitions reflect highly on the level of instruction and
dedication that a graduate student may expect while studying for either
an experimental or data-analysis LSC related PhD. I hope you take the
time to nominate your students and advisors for similar awards!

EPS Best Publication of the Month Award

The Best Publication of the Month for February was awarded to Professors
Bill Chaplin and Yvonne Elsworth and Dr Andrea Miglio, for the paper "A
sub-Mercury-sized exoplanet" published in Nature (Volume 494, Issue 7438,
pp. 452-454).


The paper reports the discovery of the smallest planet yet found outside
our solar system, a planet that is smaller than Mercury and not much
larger than the Moon. The planet was discovered by the NASA Kepler space
telescope, and Professor Chaplin led the team that used asteroseismology
to characterize the properties of the star hosting this small planet.
There are also two other planets in this system. Kepler detects planets
by the miniscule dimming of starlight as planets `transit', or pass in
front of, their host star. The fractional dimming depends on the size of
the planet relative to the size of the star; the Birmingham team led the
work that provided an accurate estimate of the size of the star, which
lies just over 200 light years from us, and it was thanks to this crucial
information that it was possible to make such clear statements about the
tiny absolute size of the planet.

Coffee Hour

Monday 18 March 2013

1030 Hours - Admission Suite Poynting Building

Just a reminder that Andy Schofield has introduced the coffee hour as an
opportunity for staff to get together, please see below the original message

I am conscious that busyness of academic life and our split site over four
buildings means there are fewer opportunities for us to meet informally as
academic staff. The colloquia and tea beforehand (which Clive organizes so
effectively) are an excellent opportunity to get together and should be seen
as an essential part of School life. I think we need more - so I would like
to try a regular morning gathering once a week:

Coffee/Tea on Mondays from 10:30-11:30 in the Admissions Suite (Poynting
building) starting on Monday 25 Feb.

The urn will be on (and of course one could support Lorna in the coffee lounge
if you want something different). By spanning the teaching hour, hopefully
people will be able to attend one or other half. The time also follows the VCs
meeting with Heads of Schools so occasionally there might be some news to
convey. It's an experiment so we will see how it goes.

College Assembly

Tuesday 19 March

1300 Hours -  G31 School of Mechanical Engineering

Paul Crowther Sheffield

The most massive stars in the local universe.

The lower limit to the mass of stars is well defined, while the upper limit remains
controversial. I shall summarise evidence in support of the currently accepted limit
and present recent VLT -based studies of the brightest members of young, nearby star
clusters which argue for a higher limit. Consideration is given to questions of
binarity using a variety of methods, while we present simulations of star clusters
which argue for an upper mass limit close to 300 solar masses. The wider
significance of this limit is discussed both for the integrated properties of
unresolved star clusters and the possibility that pair-instability supernovae exist
in the local universe, as proposed for SN 2007bi.
