Title: Cosmological simulations, AI and the high redshift Universe
Abstract: AI assistance can turn complex astrophysical supercomputer simulations into easily accessible tools. I will introduce applications to cosmology, including hybrid AI-physics codes, and a agentic system that can set up and run a billion particle simulation in seconds. As a use case for this type of modelling, I will explore the Lyman-alpha forest of intergalactic absorption in quasars and how it can both be gravitationally lensed, and also used to make large-scale maps of the intergalactic radiation intensity. I will also present cold dark matter simulation predictions for the mysterious “little red dots” seen by the Webb telescope at high redshift.
