GLIMPSE-D: An Exotic Balmer-Jump Object at z=6.20? Revisiting Photometric Selection and the Cosmic Abundance of Pop III Galaxies

Seiji Fujimoto, Yoshihisa Asada, Rohan P. Naidu +19

We present deep JWST/NIRSpec G395M spectroscopy of GLIMPSE-16043, a promising Pop III candidate originally identified through NIRCam photometry as having weak [OIII]$λ\lam…

The Deepest GLIMPSE of a Dense Gas Cocoon Enshrouding a Little Red Dot

Vasily Kokorev, John Chisholm, Rohan P. Naidu +19

The detection of strong Balmer breaks and absorption features in Little Red Dots (LRDs) suggests they host AGN embedded within dense gas envelopes, potentially powered by super-Edd…

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…

A Fleeting GLIMPSE of N/O Enrichment at Cosmic Dawn: Evidence for Wolf Rayet N Stars in a z = 6.1 Galaxy

Danielle A. Berg, Rohan P. Naidu, John Chisholm +18

We present the discovery of extreme nitrogen enrichment by Wolf Rayet nitrogen stars (WN) in the metal-poor (~10% Z_odot), lensed, compact (R_eff ~ 20 pc) galaxy RXCJ2248 at z=6.1,…

Lyα Intensity Mapping in HETDEX: Galaxy-Lyα Intensity Cross-Power Spectrum

Maja Lujan Niemeyer, Eiichiro Komatsu, José Luis Bernal +18

We present a measurement of the Lyman- (Ly) intensity mapping power spectrum from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We measure the cross-power spect…

A GLIMPSE into the very faint-end of the H+[OIII]4960,5008 luminosity function at z=7-9 behind Abell S1063

Damien Korber, Iryna Chemerynska, Lukas J. Furtak +12

We use the ultra-deep GLIMPSE JWST/NIRCam survey to constrain the faint-end of the H+[OIII]4960,5008 luminosity function (LF) down to erg/s at z=7-9 behind the len…

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…

Bursty or heavy? The surprise of bright Population III systems in the Reionization era

Alessandra Venditti, Julian B. Munoz, Volker Bromm +3

The nature of the first, so-called Population III (Pop III) stars has for long remained largely unconstrained. However, the James Webb Space Telescope (JWST) finally opened new con…

New constraints on the galactic ionizing efficiency and escape fraction at 2.5 < z < 6 based on quasar absorption spectra

Christopher Cain, Anson D'Aloisio, Julian B. Munoz

Measurements of the ionisation state of the intergalactic medium (IGM) can probe the sources of the extragalactic ionising background. We provide new measurements of the ionising e…

Modeling Galaxies in the Early Universe with Supernova Dust Attenuation

Jed McKinney, Olivia Cooper, Caitlin M. Casey +4

Supernova may be the dominant channel by which dust grains accumulate in galaxies during the first Gyr of cosmic time as formation channels important for lower redshift galaxies, e…

GLIMPSE: An ultra-faint 10 Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at

Seiji Fujimoto, Rohan P. Naidu, John Chisholm +32

Detecting the first generation of stars, Population III (PopIII), has been a long-standing goal in astrophysics, yet they remain elusive even in the JWST era. Here we present a nov…
