Speaker: Prof Mikhail Shifman, University of Minnesota
Title: Quantum Field Theory after Revolution

I give a broad review of field theory from its inception, focusing on the last
revolution –– the discovery of supersymmetric gauge theories and various
impacts it produced on the basic concepts of field theory. Some recent
applications are also discussed .

Astrophysics & Space Research Group and HiROS Group Seminar

Friday 26 May 2017, 13.00, Physics West Lecture Theatre 117
Speaker: Emma Chapman, Imperial College London
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.
