Abstract

The Epoch of Reionization (EoR) represents a fundamental phase transition in cosmic history, requiring simulation volumes large enough to capture the topology of reionization while maintaining sufficient resolution to model the sources of ionizing photons. I will present the latest results from our large-scale simulations of the EoR on exascale supercomputers, focusing on the interplay between galaxy formation and reionization, and the observational predictions for upcoming surveys.
