Galaxy Protoclusters as Drivers of Cosmic Reionization: II. Te-Based Metallicities of Lyman-α Emitters

C. Moya-Sierralta, C. L. Martin, L. F. Barrientos +15

Context. Protoclusters at reionization are thought to host a significant fraction of the cosmic star formation rate density, making them crucial for the timing and topology of reio…

Strong [OIII] $+$ H $β$ emitters dominated the ionizing budget at $z \sim 7$

Isak Wold, Sangeeta Malhotra, James Rhoads

We quantify the ionizing photon production at $z \sim 7$ using the deepest spectroscopically confirmed sample of strong [OIII] $+$ H $β$ emitters (rest-frame EW $> 740$ A) in the Abell 27…
