JWST UNCOVER: Extremely red and compact object at triply imaged by Abell 2744
Lukas J. Furtak, Adi Zitrin, Adèle Plat +29
Recent JWST/NIRCam imaging taken for the ultra-deep UNCOVER program reveals a very red dropout object at , triply imaged by the galaxy cluster Abell 274…
UNCOVERing the extended strong lensing structures of Abell 2744 with the deepest JWST imaging
Lukas J. Furtak, Adi Zitrin, John R. Weaver +18
We present a new parametric lens model for the massive galaxy cluster Abell~2744 based on the new ultra-deep JWST imaging taken in the framework of the UNCOVER program. These obser…
The JWST UNCOVER Treasury survey: Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization
Rachel Bezanson, Ivo Labbe, Katherine E. Whitaker +40
In this paper we describe the survey design for the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) Cycle 1 \JWST Treasury program, which execu…
A ~600 pc view of the strongly-lensed, massive main sequence galaxy J0901: a baryon-dominated, thick turbulent rotating disk with a clumpy cold gas ring at z = 2.259
Daizhong Liu, N. M. Förster Schreiber, R. Genzel +19
We present a high-resolution kinematic study of the massive main-sequence star-forming galaxy (SFG) SDSS J090122.37+181432.3 (J0901) at z=2.259, using 0.36 arcsec ALMA CO(3-2) and…
Galaxy kinematics and mass estimates at from ionised gas and stars
Hannah Übler, Natascha M. Förster Schreiber, Arjen van der Wel +14
We compare ionised gas and stellar kinematics of 16 star-forming galaxies (, SFR=6-86 ) at using near-infrared integral field s…
RC100: Rotation Curves of 100 Massive Star-Forming Galaxies at z=0.6-2.5 Reveal Little Dark Matter on Galactic Scales
A. Nestor Shachar, S. H. Price, N. M. Förster Schreiber +19
We analyze Ha or CO rotation curves (RCs) extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy…
JWST reveals a population of ultra-red, flattened disk galaxies at 2<z<6 previously missed by HST
Erica J. Nelson, Katherine A. Suess, Rachel Bezanson +19
With just a month of data, JWST is already transforming our view of the Universe, revealing and resolving starlight in unprecedented populations of galaxies. Although ``HST-dark" g…
The MOSDEF Survey: Probing Resolved Stellar Populations at Using a New Bayesian-defined Morphology Metric Called Patchiness
Tara Fetherolf, Naveen A. Reddy, Alice E. Shapley +12
We define a new morphology metric called "patchiness" () that is sensitive to deviations from the average of a resolved distribution, does not require the galaxy center to be de…
Kinematics and Mass Distributions for Non-Spherical Deprojected Sérsic Density Profiles and Applications to Multi-Component Galactic Systems
S. H. Price, H. Übler, N. M. Förster Schreiber +6
Using kinematics to decompose galaxies' mass profiles, including the dark matter contribution, often requires parameterization of the baryonic mass distribution based on ancillary…
Rest-frame near-infrared sizes of galaxies at cosmic noon: objects in JWST's mirror are smaller than they appeared
Katherine A. Suess, Rachel Bezanson, Erica J. Nelson +10
Galaxy sizes and their evolution over cosmic time have been studied for decades and serve as key tests of galaxy formation models. However, at these studies have been l…
Two Remarkably Luminous Galaxy Candidates at Revealed by JWST
