Two Distinct Classes of Quiescent Galaxies at Cosmic Noon Revealed by JWST PRIMER and UNCOVER
Sam E. Cutler, Katherine E. Whitaker, John R. Weaver +31
We present a measurement of the low-mass quiescent size-mass relation at Cosmic Noon (1<z<3) from the JWST PRIMER and UNCOVER treasury surveys, which highlights two distinct classe…
The UNCOVER Survey: A First-look HST+JWST Catalog of Galaxy Redshifts and Stellar Population Properties Spanning
Bingjie Wang, Joel Leja, Ivo Labbé +41
The recent UNCOVER survey with the James Webb Space Telescope (JWST) exploits the nearby cluster Abell 2744 to create the deepest view of our universe to date by leveraging strong…
UNCOVER: The growth of the first massive black holes from JWST/NIRSpec -- spectroscopic redshift confirmation of an X-ray luminous AGN at z=10.1
Andy D. Goulding, Jenny E. Greene, David J. Setton +27
The James Webb Space Telescope is now detecting early black holes (BHs) as they transition from "seeds" to supermassive BHs. Recently Bogdan et al. (2023) reported the detection of…
UNCOVER spectroscopy confirms a surprising ubiquity of AGN in red galaxies at
Jenny E. Greene, Ivo Labbe, Andy D. Goulding +31
JWST is revealing a new population of dust-reddened broad-line active galactic nuclei (AGN) at redshifts . Here we present deep NIRSpec/Prism spectroscopy from the Cycle…
DUALZ: Deep UNCOVER-ALMA Legacy High-Z Survey
Seiji Fujimoto, Rachel Bezanson, Ivo Labbe +29
We present the survey design and initial results of the ALMA Cycle 9 program of DUALZ, which aims to establish a joint ALMA and JWST public legacy field targeting the massive galax…
UNCOVER: A NIRSpec Identification of a Broad Line AGN at z = 8.50
Vasily Kokorev, Seiji Fujimoto, Ivo Labbe +29
Deep observations with JWST have revealed an emerging population of red point-like sources that could provide a link between the postulated supermassive black hole seeds and observ…
UNCOVER: A NIRSpec Census of Lensed Galaxies at z=8.50-13.08 Probing a High AGN Fraction and Ionized Bubbles in the Shadow
Seiji Fujimoto, Bingjie Wang, John Weaver +33
We present JWST NIRSpec prism spectroscopy of gravitationally lensed galaxies at found behind the massive galaxy cluster Abell 2744 in the UNCOVER Cycle 1 Treasury Prog…
The Large Magellanic Cloud's Kiloparsec Bow Shock and its Impact on the Circumgalactic Medium
David J. Setton, Gurtina Besla, Ekta Patel +3
The interaction between the supersonic motion of the Large Magellanic Cloud (LMC) and the Circumgalactic Medium (CGM) is expected to result in a bow shock that leads the LMC's gase…
Most of the photons that reionized the Universe came from dwarf galaxies
Hakim Atek, Ivo Labbé, Lukas J. Furtak +30
The identification of sources driving cosmic reionization, a major phase transition from neutral Hydrogen to ionized plasma around 600-800 Myr after the Big Bang (Dayal et al. 2018…
A high black hole to host mass ratio in a lensed AGN in the early Universe
Lukas J. Furtak, Ivo Labbé, Adi Zitrin +34
Early JWST observations have uncovered a new population of red sources that might represent a previously overlooked phase of supermassive black hole growth (Kocevski et al. 2023; M…
UNCOVER: Illuminating the Early Universe -- JWST/NIRSpec Confirmation of Galaxies
Bingjie Wang, Seiji Fujimoto, Ivo Labbe +24
Observations of high-redshift galaxies provide a critical direct test to the theories of early galaxy formation, yet to date, only three have been spectroscopically confirmed at $z…
The FENIKS Survey: Spectroscopic Confirmation of Massive Quiescent Galaxies at z ~ 3-5
Jacqueline Antwi-Danso, Casey Papovich, James Esdaile +13
The measured ages of massive, quiescent galaxies at imply that massive galaxies quench as early as . While the number of spectroscopic confirmations of quiesce…
The UNCOVER Survey: A first-look HST+JWST catalog of 60,000 galaxies near Abell 2744 and beyond
John R. Weaver, Sam E. Cutler, Richard Pan +41
In November 2022, the James Webb Space Telescope (JWST) returned deep near-infrared images of Abell 2744 -- a powerful lensing cluster capable of magnifying distant, incipient gala…
