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 $…

Large Lyman-alpha opacity fluctuations and low CMB tau in models of late reionization with large islands of neutral hydrogen extending to z<5.5

Girish Kulkarni, Laura C. Keating, Martin G. Haehnelt +4

High-redshift QSO spectra show large spatial fluctuations in the Ly-alpha opacity of the intergalactic medium on surprisingly large scales at z>~5.5. We present a radiative transfe…

Suppression of Star Formation in Low-Mass Galaxies Caused by the Reionization of their Local Neighborhood

Taha Dawoodbhoy, Paul R. Shapiro, Pierre Ocvirk +10

Photoheating associated with reionization suppressed star formation in low-mass galaxies. Reionization was inhomogeneous, however, affecting different regions at different times. T…

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…
