Double-Peaked Ly Emission during Reionization Requires Nearby Voids and a Favorable Local Ionizing Background

Hyunbae Park, Aaron Smith, Intae Jung +11

Several Lyman-alpha (Ly) emitters deep into the reionization era exhibit double-peaked Ly emission profiles, raising the question of how the intergalactic medium can transmit…

The Thermal Sunyaev-Zel'dovich Effect from the Epoch of Reionization

Ilian T. Iliev, Azizah R. Hosein, Jens Chluba +11

The thermal Sunyaev-Zel'dovich (tSZ) effect arises from inverse Compton scattering of low energy photons onto thermal electrons, proportional to the integrated electron pressure, a…

Dispersion Measures of Fast Radio Bursts through the Epoch of Reionization

Joshua J. Ziegler, Paul R. Shapiro, Taha Dawoodbhoy +13

Dispersion measures (DM) of fast radio bursts (FRBs) probe the density of electrons in the intergalactic medium (IGM) along their lines-of-sight, including the average density vers…

Constraining Reionization with Lyα Damping-Wing Absorption in Galaxy Spectra: A Machine Learning Model Based on Reionization Simulations

Hyunbae Park, Intae Jung, Hidenobu Yajima +8

Recently, NIRSpec PRISM/CLEAR observations by JWST have begun providing rest-frame UV continuum measurements of galaxies at , revealing signatures of Ly damping-wing…

Cosmic Variance and the Inhomogeneous UV Luminosity Function of Galaxies During Reionization

Taha Dawoodbhoy, Paul R. Shapiro, Pierre Ocvirk +8

When the first galaxies formed and starlight escaped into the intergalactic medium to reionize it, galaxy formation and reionization were both highly inhomogeneous in time and spac…

Reionization time of the Local Group and Local-Group-like halo pairs

Jenny G. Sorce, Pierre Ocvirk, Dominique Aubert +7

Patchy cosmic reionization resulted in the ionizing UV background asynchronous rise across the Universe. The latter might have left imprints visible in present day observations. Se…

The short ionizing photon mean free path at z=6 in Cosmic Dawn III, a new fully-coupled radiation-hydrodynamical simulation of the Epoch of Reionization

Joseph S. W. Lewis, Pierre Ocvirk, Jenny G. Sorce +13

Recent determinations of the mean free path of ionising photons (mfp) in the intergalactic medium (IGM) at are lower than many theoretical predictions. To gain insight in…

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…

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…

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…
