The Mass-Metallicity Relation and its Observational Effects at z~3-6
Zach Lewis, Michael V. Maseda, Anna de Graaff +21
The correlation between galaxy stellar mass and gas-phase metallicity, known as the mass-metallicity relation (MZR), gives key insights into the processes that govern galaxy evolut…
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…
Reionization history constraints from neural network based predictions of high-redshift quasar continua
D. Ďurovčíková, H. Katz, S. E. I. Bosman +3
Observations of the early Universe suggest that reionization was complete by , however, the exact history of this process is still unknown. One method for measuring the evo…
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…
The Formation of Spiral Galaxies: Adiabatic Compression with Young's Algorithm and the Relation of Dark Matter Haloes to Their Primordial Antecedents
Harley Katz, Stacy S. McGaugh, J. A. Sellwood +1
We utilize Young's algorithm to model the adiabatic compression of the dark matter haloes of galaxies in the THINGS survey to determine the relationship between the halo fit to the…
Galaxy Cluster Bulk Flows and Collision Velocities in QUMOND
Harley Katz, Stacy McGaugh, Peter Teuben +1
We examine the formation of clusters of galaxies in numerical simulations of a QUMOND cosmogony with massive sterile neutrinos. Clusters formed in these exploratory simulations dev…
Two Epochs of Globular Cluster Formation from Deep Fields Luminosity Functions: Implications for Reionization and the Milky Way Satellites
Harley Katz, Massimo Ricotti
The ages of globular clusters in our own Milky Way are known with precision of about \pm 1 Gyr, hence their formation at redshifts z>~3 and their role in hierarchical cosmology and…
