Cosmological Magnetogenesis: The Biermann Battery during the Epoch of Reionization
Mara Attia, Romain Teyssier, Harley Katz +4
We investigate the effect of the Biermann battery during the Epoch of Reionization (EoR) using cosmological Adaptive Mesh Refinement simulations within the framework of the SPHINX…
Introducing SPHINX-MHD: The Impact of Primordial Magnetic Fields on the First Galaxies, Reionization, and the Global 21cm Signal
Harley Katz, Sergio Martin-Alvarez, Joakim Rosdahl +10
We present the first results from SPHINX-MHD, a suite of cosmological radiation-magnetohydrodynamics simulations designed to study the impact of primordial magnetic fields (PMFs) o…
Tracing the Sources of Reionization in Cosmological Radiation Hydrodynamics Simulations
Harley Katz, Taysun Kimm, Martin G. Haehnelt +3
We use the photon flux and absorption tracer algorithm presented in Katz et al.~2018, to characterise the contribution of haloes of different mass and stars of different age and me…
Resolution Convergence in Cosmological Hydrodynamical Simulations Using Adaptive Mesh Refinement
Owain N. Snaith, Changbom Park, Juhan Kim +1
We have explored the evolution of gas distributions from cosmological simulations carried out using the RAMSES adaptive mesh refinement (AMR) code, to explore the effects of resolu…
A Census of the LyC Photons that Form the UV Background During Reionization
Harley Katz, Taysun Kimm, Martin Haehnelt +3
We present a new, on-the-fly photon flux and absorption tracer algorithm designed to directly measure the contribution of different source populations to the metagalactic UV backgr…
RAMSES-RT: Radiation hydrodynamics in the cosmological context
Joakim Rosdahl, Jeremy Blaizot, Dominique Aubert +2
We present a new implementation of radiation hydrodynamics (RHD) in the adaptive mesh refinement (AMR) code RAMSES. The multi-group radiative transfer (RT) is performed on the AMR…
