The Sherwood-Relics simulations

The Sherwood-Relics suite consists of over 200 simulations and focuses on cosmic reionization and its impact on the intergalactic medium (IGM) and Lyman-alpha forest.

It includes runs with a new lightweight hybrid radiative transfer/cosmological hydrodynamical simulation technique that I have developed to capture radiative transfer effects during patchy cosmic reionization. It allows following the spatial fluctuations of IGM temperature and pressure-smoothing that are seeded by patchy reionzation and that persist for a significant amount of time after its completion. A full description of the technique is provided here.
