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…
Line Intensity Mapping Prediction from the Cosmic Dawn (CoDa) III Simulation for H from Galaxies and the Intergalactic Medium during the Epoch of Reionization
Eugene Hyeonmin Lee, Joohyun Lee, Paul R. Shapiro +13
The evolution of large-scale structure, galaxies and the intergalactic medium (IGM) during the Epoch of Reionization (EoR) can be probed by upcoming Line Intensity Mapping (LIM) ex…
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…
New insight on the nature of cosmic reionizers from the CEERS survey
S. Mascia, L. Pentericci, A. Calabrò +29
The Epoch of Reionization (EoR) began when galaxies grew in abundance and luminosity, so their escaping Lyman continuum (LyC) radiation started ionizing the surrounding neutral int…
The signature of galaxy formation models in the power spectrum of the hydrogen 21cm line during reionization
Joseph S. W. Lewis, Annalisa Pillepich, Dylan Nelson +2
Observations of the 21cm line of neutral hydrogen are poised to revolutionize our knowledge of cosmic reionization and the high-redshift population of galaxies. However, harnessing…
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…
DUSTiER (DUST in the Epoch of Reionization): dusty galaxies in cosmological radiation-hydrodynamical simulations of the Epoch of Reionization with RAMSES-CUDATON
Joseph S. W. Lewis, Pierre Ocvirk, Yohan Dubois +4
In recent years, interstellar dust has become a crucial topic in the study of the high and very high redshift Universe. Evidence points to the existence of high dust masses in mass…
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…
Lyman-alpha transmission properties of the intergalactic medium in the CoDaII simulation
Max Gronke, Pierre Ocvirk, Charlotte Mason +10
The decline in abundance of Lyman- (Ly) emitting galaxies at is a powerful and commonly used probe to constrain the progress of cosmic reionization. We use the…
