Title: Introducing the Lumina simulation
Abstract:
Reionisation marks the phase transition from a neutral, cold intergalactic medium (IGM) to an ionised IGM. The process can be divided into two phases: HI and HeI reionisation, driven mostly by stars, and a later HeII reionisation, driven by black holes.
Self-consistently simulating reionisation requires a high enough resolution and a realistic galaxy formation model to resolve the sources, a large enough simulation volume to resolve the largest ionised bubbles and radiation transport on-the-fly.
In this talk, I present the Lumina simulation, which self-consistently follows the evolution of the IGM through HI, HeI, and HeII reionisation, together with stellar, black-hole (BH), and X-ray sources, to z = 3.
It uses the Illustris TNG galaxy formation, coupled to GPU-accelerated radiation transport, in a box with a side length of 500 cMpc.
I will present results on the large-scale structure evolution, summary statistics such as the reionisation histories of HI, HeI, and HeII, as well as the morphology and cosmic variance of reionisation.
