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…

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…

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…

Chasing the beginning of reionization in the JWST era

Christopher Cain, Garett Lopez, Anson D'Aloisio +4

Recent JWST observations at may imply galactic ionizing photon production above prior expectations. Under observationally motivated assumptions about escape fractions, thes…

On the correlation between Ly forest opacity and galaxy density in late reionization models

Nakul Gangolli, Anson D'Aloisio, Christopher Cain +2

The relationship between Ly forest opacity and local galaxy density (the opacity-density relation) is a key observational test of late reionization models. Using narrow-band su…

Quantifying Lyman- emissions from reionization fronts

Bayu Wilson, Anson D'Aloisio, Christopher Cain +2

During reionization, intergalactic ionization fronts (I-fronts) are sources of Ly line radiation produced by collisional excitation of hydrogen atoms within the fronts. In prin…
