Lyman-alpha opacities at z=4-6 require low mass, radiatively-suppressed galaxies to drive cosmic reionization
Pierre Ocvirk, Joseph S. W. Lewis, Nicolas Gillet +4
The high redshift Lyman-alpha forest, in particular the Gunn-Peterson trough, is the most unambiguous signature of the neutral to ionized transition of the intergalactic medium (IG…
Galactic ionising photon budget during the Epoch of Reionisation in the Cosmic Dawn II simulation
Joseph S. W. Lewis, Pierre Ocvirk, Dominique Aubert +10
Cosmic Dawn ("CoDa") II yields the first statistically-meaningful determination of the relative contribution to reionization by galaxies of different halo mass, from a fully-couple…
A deep learning model to emulate simulations of cosmic reionization
Jonathan Chardin, Grégoire Uhlrich, Dominique Aubert +4
We present a deep learning model trained to emulate the radiative transfer during the epoch of cosmological reionization. CRADLE (Cosmological Reionization And Deep LEarning) is an…
Cosmic Dawn II (CoDa II): a new radiation-hydrodynamics simulation of the self-consistent coupling of galaxy formation and reionization
Pierre Ocvirk, Dominique Aubert, Jenny G. Sorce +10
Cosmic Dawn II (CoDa II) is a new, fully-coupled radiation-hydrodynamics simulation of cosmic reionization and galaxy formation and their mutual impact, to redshift . With $…
Impact of the reduced speed of light approximation on the post-overlap neutral hydrogen fraction in numerical simulations of the epoch of reionization
P. Ocvirk, D. Aubert, J. Chardin +2
The reduced speed of light approximation is used in a variety of simulations of the epoch of reionization and galaxy formation. Its popularity stems from its ability to drastically…
Impact of the reduced speed of light approximation on ionization front velocities in cosmological simulations of the epoch of reionization
Nicolas Deparis, Dominique Aubert, Pierre Ocvirk +2
Coupled radiative-hydrodynamics simulations of the epoch of reionization aim to reproduce the propagation of ionization fronts during the transition before the overlap of HII regio…
The Inhomogeneous Reionization Times of Present-day Galaxies
Dominique Aubert, Nicolas Deparis, Pierre Ocvirk +6
Today's galaxies experienced cosmic reionization at different times in different locations. For the first time, reionization ( ionized) redshifts, , at the location of t…
EMMA: an AMR cosmological simulation code with radiative transfer
Dominique Aubert, Nicolas Deparis, Pierre Ocvirk
EMMA is a cosmological simulation code aimed at investigating the reionization epoch. It handles simultaneously collisionless and gas dynamics, as well as radiative transfer physic…
