Antoine Klein will give a presentation
Title: Fourier-domain waveforms for eccentric precessing systems

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.

Physics Colloquium

Wednesday 21 November 2018, 4pm, Poynting Small Lecture Theatre S06
Speaker: Niek van Hulst - ICFO (Barcelona)
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.

Astronomy in the City

Wednesday 21 November 2018, 6pm, Poynting Large Lecture Theatre

Aaron Jones will discuss his research for the LIGO gravitational wave
detectors. In addition to this Aaron, and artist Leon Trimble will showcase
a musical instrument they have developed out of gravitational wave detector
technology.
Tickets are now available from https://astrointhecity11212018.eventbrite.co.uk

The first talk begins at 6:15 pm, in the Large Lecture Theatre of the
Poynting Physics Building on the University's Edgbaston campus. Please
arrive by 6:10 pm to be entered into the ballot for trips to the Observatory.
Visits from school or other groups are welcome; please get in touch if you
have questions. The other Astronomy in the City events of this season will
be on Wednesday 23 January 2019 and Wednesday 6 March 2019.

Astrophysics & Space Research Group and HiROS Group Seminar

Friday 23 November 2018, 1pm, Physics West 106
Speaker: Yan-Chuan Cai, Edinburgh University
Title: Cosmology with the cosmic web

On large scales, the matter distribution of the Universe follows a web-like
pattern, consisting of knot (cluster), filament, sheet and void. The
cosmic-web is a non-Gaussian field, containing invaluable information about
cosmology and astrophysics. I will summarise recent research activities in
trying to extract this information. I will highlight opportunities and
challenges for cluster cosmology, and show evidence for gas filaments between
pairs of galaxies.
