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…

The Absence of [CII] 158m Emission in Spectroscopically-Confirmed Galaxies at

N. Laporte, H. Katz, R. S. Ellis +8

The scatter in the relationship between the strength of [CII] 158m emission and the star formation rate at high-redshift has been the source of much recent interest. Although th…

How to Quench a Dwarf Galaxy: The Impact of Inhomogeneous Reionization on Dwarf Galaxies and Cosmic Filaments

Harley Katz, Marius Ramsoy, Joakim Rosdahl +8

We use the SPHINX suite of high-resolution cosmological radiation hydrodynamics simulations to study how spatially and temporally inhomogeneous reionization impacts the baryonic co…

The baryonic Tully-Fisher relation for different velocity definitions and implications for galaxy angular momentum

Federico Lelli, Stacy S. McGaugh, James M. Schombert +2

We study the baryonic Tully-Fisher relation (BTFR) at z=0 using 153 galaxies from the SPARC sample. We consider different definitions of the characteristic velocity from HI and H-a…

deepCool: Fast and Accurate Estimation of Cooling Rates in Irradiated Gas with Artificial Neural Networks

Thomas P. Galligan, Harley Katz, Taysun Kimm +4

Accurate models of radiative cooling are a fundamental ingredient of modern cosmological simulations. Without cooling, accreted baryons will not efficiently dissipate their energy…

Understanding the escape of LyC and Ly photons from turbulent clouds

Taysun Kimm, Jeremy Blaizot, Thibault Garel +5

Understanding the escape of Lyman continuum (LyC) and Lyman alpha (Lya) photons from molecular clouds is one of the keys to constraining the reionization history of the Universe an…
