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…

Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation

Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13

Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…

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…
