Characterising the epoch of reionisation using the cross-correlation of the kSZ effect and CMB lensing
Niall MacCrann, Christopher Cain, Aleksandra Kusiak +5
We investigate the cross-correlation of the kinematic Sunyaev-Zeldovich (kSZ) effect with lensing of the cosmic microwave background (CMB) as a probe of the epoch of reionisation.…
An emulator for the ionizing photon mean free path in ultra-high resolution simulations: the implications of mean free path measurements for the reionization history
Hurum Maksora Tohfa, Christopher Cain, Matthew McQuinn +1
Measurements of the mean free path of ionizing photons from high-redshift quasar spectra at - constrain the reionization history, but interpreting them requires modeli…
Fireworks at Cosmic Dawn: relieving BAO-CMB tensions with the Pop III.1 Flash
Yash Aggarwal, Christopher Cain, Garett Lopez +4
A Cosmic Microwave Background (CMB) optical depth of , several in excess of the latest Planck low- EE polarization measurement, has been proposed as a way t…
A self-consistent analytical model for both the photoionization rate and reionization history
Christopher Cain, Kevin S. Croker, Anson D'Aloisio +4
Recent developments at the intersection of cosmology and astrophysics have highlighted the need for improved analytical models of observables that probe the Epoch of Reionization.…
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…
Introducing SAGUARO -- Simulating IGM Evolution and Environments At High Resolution: Setup and First Results
Christopher Cain, Aloha Das, Anson D'Aloisio +7
Small-scale physics in the intergalactic medium (IGM) plays a crucial role in shaping the progress of cosmic reionization and several high-redshift observables that probe this peri…
