Galaxy Protoclusters as Drivers of Cosmic Reionization: I. Bubble Overlap at Redshift z ~ 7 in LAGER-z7OD1
Crystal L. Martin, Weida Hu, Isak G. B. Wold +17
Since the launch of JWST, the sample size of reionization-era Lyman-alpha-emitters (LAEs) has been steadily growing; yet inferences about the neutral hydrogen fraction in the inter…

Faint active galactic nuclei supplied 31-75% of hydrogen-ionizing photons at z>5
Mainak Singha, Sangeeta Malhotra, James Ely Rhoads
The origin of the ionizing photons that completed hydrogen reionization remains debated. Using recent JWST and ground-based surveys at 4.5 <= z <= 6.5, we construct a unified rest-…

The atomic gas properties of Green Pea galaxies: Connections to Lyman continuum leakage
Archishman Khasnovis, Nissim Kanekar, Sangeeta Malhotra +1
We have used the Green Bank Telescope to search for H{\sc{i}} 21\,cm emission from 30 Green Pea galaxies (GPs) at , obtaining 7 detections of H{\sc{i}} 21\,cm…
