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…
Reconstruction of Radio Relics and X-ray Tails in an Off-axis Cluster Merger: Hydrodynamical Simulations of A115
Wonki Lee, M. James Jee, Hyesung Kang +3
Although a merging galaxy cluster is a useful laboratory to study many important astrophysical processes and fundamental physics, only limited interpretations are possible without…
Magnetogenesis at Cosmic Dawn: Tracing the Origins of Cosmic Magnetic Fields
Harley Katz, Sergio Martin-Alvarez, Julien Devriendt +2
Despite their ubiquity, the origin of cosmic magnetic fields remains unknown. Various mechanisms have been proposed for their existence including primordial fields generated by inf…
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…
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…
