Galaxy Underdensities Host the Clearest IGM Ly Transmission and Indicate Anisotropic Reionization
Yongda Zhu, George D. Becker, Anson D'Aloisio +6
How galaxies drive reionization and what governs its geometry remain fundamental questions. We present JWST/NIRCam wide-field slitless spectroscopy (WFSS) observations toward two o…
A long time ago in an LAE far, far away: a signpost of early reionization or a nascent AGN at ?
Joshua Cohon, Christopher Cain, Rogier Windhorst +3
The JADES survey recently reported the discovery of JADES-GS-z13-1-LA at , the highest redshift Ly emitter (LAE) ever observed. This observation suggests that either the…
Probing the ionizing photon output of galaxies near cosmic dawn with the patchy kSZ effect
Garett Lopez, Anson D'Aloisio, Christopher Cain
A key result from JWST's first cycles is that galaxy formation was well underway by . The implications of these early galaxies for reionization are less clear, however. The C…
The CMB optical depth constrains the duration of reionization
Christopher Cain, Alexander Van Engelen, Kevin S. Croker +3
Recently, it was pointed out that invoking a large value of the CMB optical depth, , could help resolve tensions between DESI DR2 BAO data and the CMB. This is…
Kiloparsec-scale turbulence driven by reionization may grow intergalactic magnetic fields
Christopher Cain, Matthew McQuinn, Evan Scannapieco +2
The intergalactic medium (IGM) underwent intense heating that resulted in pressure disequilibrium in the wake of ionization fronts during cosmic reionization. The dynamical relaxat…
New constraints on the galactic ionizing efficiency and escape fraction at 2.5 < z < 6 based on quasar absorption spectra
Christopher Cain, Anson D'Aloisio, Julian B. Munoz
Measurements of the ionisation state of the intergalactic medium (IGM) can probe the sources of the extragalactic ionising background. We provide new measurements of the ionising e…
Cross-correlating the patchy screening and kinetic Sunyaev-Zel'dovich effects as a new probe of reionization
Darby Kramer, Alexander van Engelen, Christopher Cain +5
The kinetic Sunyaev-Zel'dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era. The kSZ effect is a…
