CEERS MIRI Imaging: Data Reduction and Quality Assessment
Guang Yang, Casey Papovich, Micaela Bagley +35
The Cosmic Evolution Early Release Science Survey (CEERS), targeting the Extended Groth Strip extragalactic field, is one of the JWST Director's Discretionary Early Release Science…
The quasi-star model for Little Red Dots: potential and challenges
Fabrizio Gentile, Mauro Giavalisco, Emanuele Daddi +25
(Abridged) Little Red Dots (LRDs) are a class of sources discovered by JWST observationally defined by a "V-shaped" rest-frame UV-Optical SED, a compact or unresolved morphology, a…
Improved Identification of Satellite Trails in ACS/WFC Imaging Using a Modified Radon Transform
David V. Stark, Norman Grogin, Jenna Ryon +1
We present a new approach to identify satellite trails (or other linear artifacts) in ACS/WFC imaging data using a modified Radon Transform. We demonstrate that this approach is se…
GOODS-Herschel and CANDELS: The Morphologies of Ultraluminous Infrared Galaxies at z~2
Jeyhan S. Kartaltepe, Mark Dickinson, David M. Alexander +40
Using deep 100-160 micron observations in GOODS-S from the GOODS-H survey, combined with HST/WFC3 NIR imaging from CANDELS, we present the first morphological analysis of a complet…
JWST NIRCam Photometry: A Study of Globular Clusters Surrounding Bright Elliptical Galaxy VV 191a at z=0.0513
Jessica M. Berkheimer, Timothy Carleton, Rogier A. Windhorst +22
James Webb Space Telescope NIRCam images have revealed 154 reliable globular cluster (GC) candidates around the elliptical galaxy VV~191a after subtracting 34 likely i…
CEERS: 7.7 m PAH Star Formation Rate Calibration with JWST MIRI
Kaila Ronayne, Casey Papovich, Guang Yang +33
We test the relationship between UV-derived star formation rates (SFRs) and the 7.7 m polycyclic aromatic hydrocarbon (PAH) luminosities from the integrated emission of galaxie…
Clumpy Galaxies in CANDELS. I. The Definition of UV Clumps and the Fraction of Clumpy Galaxies at 0.5<z<3
Yicheng Guo, Henry C. Ferguson, Eric F. Bell +19
Although giant clumps of stars are crucial to galaxy formation and evolution, the most basic demographics of clumps are still uncertain, mainly because the definition of clumps has…
