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 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…

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…

ESpRESSO -- Forward modeling Roman Space Telescope spectroscopy

Austen Gabrielpillai, Isak G. B. Wold, Sangeeta Malhotra +4

We describe the software package - [E]xtragalactic [Sp]ectroscopic [R]oman [E]mulator and [S]imulator of [S]ynthetic [O]bjects, created to emulate the slitless…

Discovery of Local Analogs to JWST's Little Red Dots

Ruqiu Lin, Zhen-Ya Zheng, Chunyan Jiang +12

Recently, the James Webb Space Telescope (JWST) has revealed a new class of high redshift (high-, ) compact galaxies which are red in the rest-frame optical and blue in the…

A resolved Lyman-Alpha profile with doubly peaked emission at z~7

C. Moya-Sierralta, J. González-López, L. Infante +7

The epoch of reionization is a landmark in structure formation and galaxy evolution. How it happened is still not clear, especially regarding which population of objects was respon…

UNCOVERing the Faint-End of the z=7 [OIII] Luminosity Function with JWST's F410M Medium Bandpass Filter

Isak G. B. Wold, Sangeeta Malhotra, James E. Rhoads +2

Strong emission from doubly ionized oxygen is a beacon for some of the most intensely star forming galaxies known. JWST enables the search for this beacon in the early universe wit…

A lack of LAEs within 5Mpc of a luminous quasar in an overdensity at z=6.9: potential evidence of quasar negative feedback at protocluster scales

Trystan S. Lambert, R. J. Assef, C. Mazzucchelli +13

High-redshift quasars are thought to live in the densest regions of space which should be made evident by an overdensity of galaxies around them. However, campaigns to identify the…
