MEGATRON: the impact of non-equilibrium effects and local radiation fields on the circumgalactic medium at cosmic noon
The episode discusses a paper titled "MEGATRON: the impact of non-equilibrium effects and local radiation fields on the circumgalactic medium at cosmic noon." The hosts explain that modeling the Circumgalactic Medium (CGM) as an equilibrium system is insufficient. Non-equilibrium chemical processes and local radiation fields shift ion locations, potentially changing observations like H I absorber covering fractions by up to forty percent. The paper suggests refining resolution based on cooling length for more accurate simulations.
