Modelling the epoch of reionisation on a computer

Oliver Zier 
ITC Fellow

Abstract: Recent advancements in observational instruments such as JWST, ALMA,  HERA, and many others are revolutionizing our understanding of primitive galaxies and the Epoch of Reionisation (EoR). Hydrogen reionization in the IGM itself is inherently a multi-scale problem: driven by the combined radiation from individual stars formed in the ISM and reaching inhomogeneities of hundreds of cMpc. In this talk, I will present two complementary simulation projects: 
THESAN-ZOOM is a suite of high-resolution radiation-hydrodynamic zoom-ins that resolve ISM structure and star formation in high-redshift galaxies, enabling predictive links to observables such as escape fractions, nebular emission, and morphology.
THESAN and THESAN-XL are cosmological-volume simulations designed to capture the timing and topology of reionisation and its large-scale imprints, including 21-cm statistics accessible to current and upcoming surveys.
