The Roman eXtreme Deep Field (RXDF)

Haojing Yan, Anton M. Koekemoer, Yue Shen +127

The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…

Strong [OIII]H emitters dominated the ionizing budget at

Isak Wold, Sangeeta Malhotra, James Rhoads

We quantify the ionizing photon production at using the deepest spectroscopically confirmed sample of strong [OIII]H emitters (rest-frame EW A) in the Abell 27…

Going Wide and Deep with Roman: The z~6-9 UV luminosity function in a Roman Deep Field

Micaela B. Bagley, Steven L. Finkelstein, James Rhoads +4

We present a trade study of possible ultra-deep surveys with the Nancy Grace Roman Space Telescope, optimizing the depth-area-filter parameter space for high-redshift galaxy scienc…

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…
