The Sherwood-Relics simulations: overview and impact of patchy reionization and pressure smoothing on the intergalactic medium

Understand

We present the Sherwood-Relics simulations, a new suite of large cosmological hydrodynamical simulations aimed at modelling the intergalactic medium (IGM) during and after the cosmic reionization of hydrogen.

• The suite consists of over 200 simulations that cover a wide range of astrophysical and cosmological parameters.
• It also includes simulations that use a new lightweight hybrid scheme for treating radiative transfer effects.
• This scheme follows the spatial variations in the ionizing radiation field, as well as the associated fluctuations in IGM temperature and pressure smoothing.
