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…

Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75
We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…
Discovery of red galaxy candidates at z ~ 12: Early dust growth or significant nebular emission with high-temperature stars?
Ikki Mitsuhashi, Katherine A. Suess, Joel Leja +18
We report the discovery of two z ~ 12 galaxy candidates with unusually red UV slopes (betaUV ~> -1.5), and probe the origin of such colors at cosmic dawn. From Prospector fits to t…
A GLIMPSE of Intermediate Mass Black holes in the epoch of reionization: Witnessing the Descendants of Direct Collapse?
Qinyue Fei, Seiji Fujimoto, Rohan P. Naidu +17
JWST has revealed an abundance of supermassive black holes (BHs) in the early Universe, and yet the lowest mass seed black holes that gave rise to these populations remain elusive.…
Feeding the Dead: Neutral Gas Inflow in a Long-Quenched Ancient Massive Galaxy at Observed with JWST/NIRSpec
Davide Bevacqua, Danilo Marchesini, Paolo Saracco +16
We report the spectroscopic detection of neutral gas inflow into a massive () quiescent galaxy observed at with JWST. F…
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…
What you see is what you get: empirically measured bolometric luminosities of Little Red Dots
Jenny E. Greene, David J. Setton, Lukas J. Furtak +27
New populations of red active galactic nuclei (known as ``Little Red Dots'') discovered by JWST exhibit remarkable spectral energy distributions. Leveraging X-ray through far-infra…
A massive and evolved slow-rotating galaxy in the early Universe
Ben Forrest, Adam Muzzin, Danilo Marchesini +15
In the contemporary Universe, most galaxies are supported by ordered rotation, yet a significant subset of the most massive and quiescent systems are dominated by random stellar mo…
MINERVA: A NIRCam Medium Band and MIRI Imaging Survey to Unlock the Hidden Gems of the Distant Universe
Adam Muzzin, Katherine A. Suess, Danilo Marchesini +81

Taking a Break at Cosmic Noon: Continuum-selected Low-mass Galaxies Require Long Burst Cycles
Abby Mintz, David J. Setton, Jenny E. Greene +25
While bursty star formation in low-mass galaxies has been observed in local populations and reproduced in simulations, the dormant phase of the burst cycle has not been well studie…
Measuring Emission Lines with JWST-MegaScience Medium-Bands: A New Window into Dust and Star Formation at Cosmic Noon
Brian Lorenz, Katherine A. Suess, Mariska Kriek +23
We demonstrate the power of JWST-NIRCam medium-band photometry to measure emission line fluxes and study dust and star formation properties of galaxies at cosmic noon. In this work…
The Structure and Formation Histories of Low-Mass Quiescent Galaxies in the Abell 2744 Cluster Environment
Sam E. Cutler, John R. Weaver, Katherine E. Whitaker +21
