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…

An Extremely-red, UV-bright, and Extended Galaxy at z~6 in PRIMER/UDS: An Early Massive Galaxy Caught Quenching after an Obscured Starburst?

Nadara Hudson, Ryan Endsley, John Chisholm

JWST continues to reveal an astonishing number of massive quiescent galaxies at , with number densities higher than model predictions. NIRSpec spectra imply…

Spatially Resolved Physical Properties of Young Star Clusters and Star-forming Clumps in the Brightest z>6 Galaxy, the Strongly Lensed Cosmic Spear at z=6.2

Abdurro'uf, Dan Coe, Tom Resseguier +49

We present spatially resolved analysis of stellar populations in the brightest galaxy known to date (AB mag 23), the strongly lensed MACS0308zD1 (dubbed the ``Cosmic Spear…

VENUS: When Red meets Blue -- A multiply imaged Little Red Dot with an apparent blue companion behind the galaxy cluster Abell 383

Miriam Golubchik, Lukas J. Furtak, Joseph F. V. Allingham +50

We report the discovery of a doubly-imaged Little Red Dot (LRD) candidate behind the galaxy cluster Abell 383, which we dub A383-LRD1. Initially classified as a dropout galaxy in H…

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…
