Exascale Reionization Simulations in the SKA and JWST Era – ExaSKAle

ExaSKAle aims to model the reionisation epoch using cosmological simulations, at a time when the first JWST results are available and in preparation for the advent of SKA data. The project is based on the development and use of the new AMR code Dyablo, developed for hybrid and exascale architectures and adapted to cosmological reionisation. It will then be used to produce large-scale simulations with sufficient resolution to predict the 21cm signal and model the physics of galaxies at high redshift. These simulations will feed our tools for interpreting the SKA radio signal, based on the topology of reionisation times and their reconstruction using machine learning. These results will also be used to continue our studies on the link between galaxies in the Universe at z>6 and the intergalactic medium, in a context dominated by JWST data.
