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…
