Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters
Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14
We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…
JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon
Chloë E. Benton, Erica J. Nelson, Tim B. Miller +10
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon -- the peak of cosmic star formation history -- appear disk-dominated, leaving the origin of the…
JADES Ultra-red Flattened Objects: Morphologies and Spatial Gradients in Color and Stellar Populations
Justus L. Gibson, Erica Nelson, Christina C. Williams +20
One of the more surprising findings after the first year of JWST observations is the large number of spatially extended galaxies (ultra-red flattened objects, or UFOs) among the op…
A Size Estimate for Galaxy GN-z11
James O. Baldwin, Erica Nelson, Benjamin D. Johnson +5
GN-z11 is the highest redshift galaxy spectroscopically confirmed with the Hubble Space Telescope (HST). Previous measurements of the effective radius of GN-z11 utilized galfit, wh…
The galaxies missed by Hubble and ALMA: the contribution of extremely red galaxies to the cosmic census at 3<z<8
Christina C. Williams, Stacey Alberts, Zhiyuan Ji +33
Using deep JWST imaging from JADES, JEMS and SMILES, we characterize optically-faint and extremely red galaxies at that were previously missing from galaxy census estimates.…
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…
Spatially Resolved Properties of High Redshift Galaxies in the SMACS0723 JWST ERO Field
Clara Giménez-Arteaga, Pascal A. Oesch, Gabriel B. Brammer +10
We present the first spatially resolved measurements of galaxy properties in the JWST ERO SMACS0723 field. We perform a comprehensive analysis of five galaxies with spectro…
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 COS CGM Compendium. IV. Effects of Varying Ionization Backgrounds on Metallicity Determinations in the z < 1 Circumgalactic Medium
Justus L. Gibson, Nicolas Lehner, Benjamin D. Oppenheimer +3
Metallicity estimates of circumgalactic gas based on absorption line measurements typically require photoionization modeling to account for unseen ionization states. We explore the…
