JWST's GLIMPSE: an overview of the deepest probe of early galaxy formation and cosmic reionization

Hakim Atek, John Chisholm, Vasily Kokorev +44

We present an overview of the JWST GLIMPSE program, highlighting its survey design, primary science goals, gravitational lensing models, and first results. GLIMPSE provides ultra-d…

Neutral hydrogen in and around galaxies during the Epoch of Reionization

V. Gelli, C. Mason, A. Pallottini +9

JWST spectra revealing Lyman- (Ly) absorption in galaxies offer a unique probe of reionization's earliest stages. However, disentangling absorption by the incr…

The first GLIMPSE of the faint galaxy population at Cosmic Dawn with JWST: The evolution of the ultraviolet luminosity function across z~9-15

Iryna Chemerynska, Hakim Atek, Lukas J. Furtak +27

Using ultra-deep JWST NIRCam imaging from the GLIMPSE Survey, enhanced by gravitational lensing of the AbellS1063 cluster, we investigate the faintest galaxies ever observed in the…

A Glimpse of the New Redshift Frontier Through Abell S1063

Vasily Kokorev, Hakim Atek, John Chisholm +31

We report the discovery of two galaxy candidates at redshifts between in JWST observations from the GLIMPSE survey. These robust sources were identified using a combi…

Constraints on the early Universe star formation efficiency from galaxy clustering and halo modeling of H and [O III] emitters

Marko Shuntov, Pascal A. Oesch, Sune Toft +13

We develop a theoretical framework to provide observational constraints on the early Universe galaxy-halo connection by combining measurements of the UV luminosity function (UVLF)…

Temporarily quiescent galaxies at cosmic dawn: probing bursty star formation

Viola Gelli, Andrea Pallottini, Stefania Salvadori +4

The bursty, time-variable nature of star formation in the first billion years, as revealed by JWST, drives phases of temporary quiescence in low-mass galaxies that quench after sta…
