Join Joe McCaffrey, Department of Theoretical Physics, for his talk on:
Understanding the High-Redshift Universe using Cosmological Simulations
Abstract:
With the launch of the next generation of space telescopes such as JWST and the planned launched of gravitational observatory LISA, we are at a time where we are able to peer further back into the history of the Universe than ever before. With this comes the chance to test our current cosmological models and theories through the use of cosmological simulations.
I will be discussing the recent discoveries of high mass, high redshift galaxies with JWST, what they mean for our best theory of the Universe, ΛCDM, and what numerical simulations have to say about their existence. I will also be discussing how high redshift simulations can help us in our understanding of black hole formation models by using simulations to predict regions where heavy black hole seeds may form, and how the existence of these seeds can be probed using LISA (due to be launched late 2030's).
