An unambiguous AGN and a Balmer break in an Ultraluminous Little Red Dot at z=4.47 from Ultradeep UNCOVER and All the Little Things Spectroscopy
Ivo Labbe, Jenny E. Greene, Jorryt Matthee +37
We present a detailed exploration of the most optically-luminous Little Red Dot (erg/s, erg/s, F444W=22AB) found to date. Located in the Abell 2744 fie…
JWST UNCOVERs the Optical Size - Stellar Mass Relation at : Rapid Growth in the Sizes of Low Mass Galaxies in the First Billion Years of the Universe
Tim B. Miller, Katherine A. Suess, David J. Setton +21
We study the rest-frame optical and ultraviolet morphology of galaxies in the first billion years of the Universe. Using JWST data from the UNCOVER and MegaScience surveys targetin…
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…
An Hα view of galaxy build-up in the first 2 Gyr: luminosity functions at z~4-6.5 from NIRCam/grism spectroscopy
Alba Covelo-Paz, Emma Giovinazzo, Pascal A. Oesch +22
The Hα nebular emission line is an optimal tracer for recent star formation in galaxies. With the advent of JWST, this line has recently become observable at z>3 for the first time…
UNCOVERing the High-redshift AGN Population among Extreme UV Line Emitters
Helena Treiber, Jenny Greene, John R. Weaver +23
JWST has revealed diverse new populations of high-redshift () AGN and extreme star-forming galaxies that challenge current models. In this paper, we use rest-frame UV em…
The Small Sizes and High Implied Densities of `Little Red Dots' with Balmer Breaks Could Explain Their Broad Emission Lines Without an AGN
Josephine F. W. Baggen, Pieter van Dokkum, Gabriel Brammer +10
Early JWST studies found an apparent population of massive, compact galaxies at redshifts . Recently three of these galaxies were shown to have prominent Balmer breaks,…
The UNCOVER Survey: First Release of Ultradeep JWST/NIRSpec PRISM spectra for ~700 galaxies from z~0.3-13 in Abell 2744
Sedona H. Price, Rachel Bezanson, Ivo Labbe +38
We present the design and observations of low resolution JWST/NIRSpec PRISM spectroscopy from the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVE…
Medium Bands, Mega Science: a JWST/NIRCam Medium-Band Imaging Survey of Abell 2744
Katherine A. Suess, John R. Weaver, Sedona H. Price +39
In this paper, we describe the "Medium Bands, Mega Science" JWST Cycle 2 survey (JWST-GO-4111) and demonstrate the power of these data to reveal both the spatially-integrated and s…
