We report the serendipitous discovery of an extended stellar halo surrounding the low-mass galaxy Ark 227 (; d=35 Mpc) in deep JWST NIRCam imaging from…
FRESCO: An extended, massive, rapidly rotating galaxy at z=5.3
Erica J. Nelson, Gabriel Brammer, Clara Gimenez-Arteaga +43
With the remarkable sensitivity and resolution of JWST in the infrared, measuring rest-optical kinematics of galaxies at has become possible for the first time. This study pi…
NOEMA reveals the true nature of luminous red JWST z>10 galaxy candidates
R. A. Meyer, L. Barrufet, L. A. Boogaard +3
The first year of JWST has revealed a surprisingly large number of luminous galaxy candidates beyond . While some galaxies have already been spectroscopically confirmed, ther…
JWST Reveals Widespread AGN-Driven Neutral Gas Outflows in Massive z ~ 2 Galaxies
Rebecca L. Davies, Sirio Belli, Minjung Park +15
We use deep JWST/NIRSpec R~1000 slit spectra of 113 galaxies at 1.7 < z < 3.5, selected from the mass-complete Blue Jay survey, to investigate the prevalence and typical properties…
Unveiling the hidden universe with JWST: The contribution of dust-obscured galaxies to the stellar mass function at
R. Gottumukkala, L. Barrufet, P. A. Oesch +17
With the advent of JWST, we can probe the rest-frame optical emission of galaxies at with high sensitivity and spatial resolution, making it possible to accurately characteri…
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…
Mapping dusty galaxy growth at with FRESCO: Detection of H in submm galaxy HDF850.1 and the surrounding overdense structures
Thomas Herard-Demanche, Rychard J. Bouwens, Pascal A. Oesch +21
We report the detection of a 13 H emission line from HDF850.1 at using the FRESCO NIRCam F444W grism observations. Detection of H in HDF850.1 is notewort…
EIGER V. Characterizing the Host Galaxies of Luminous Quasars at
Minghao Yue, Anna-Christina Eilers, Robert A. Simcoe +6
We report {\em JWST}/NIRCam measurements of quasar host galaxy emissions and supermassive black hole (SMBH) masses for six quasars at in the \textit{Emission-line galax…
Accelerated Formation of Ultra-Massive Galaxies in the First Billion Years
Mengyuan Xiao, Pascal Oesch, David Elbaz +35
Recent JWST observations have revealed an unexpected abundance of massive galaxy candidates in the early Universe, extending further in redshift and to lower luminosity than what h…
Extending the Chemical Reach of the H3 Survey: Detailed Abundances of the Dwarf-galaxy Stellar Stream Wukong/LMS-1
Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu +10
We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < \rm[Fe/H] \lesssim -…
Star Formation Shut Down by Multiphase Gas Outflow in a Galaxy at a Redshift of 2.45
Sirio Belli, Minjung Park, Rebecca L. Davies +15
Large-scale outflows driven by supermassive black holes are thought to play a fundamental role in suppressing star formation in massive galaxies. However, direct observational evid…
