The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk
Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12
A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…
Improving Posterior Inference of Galaxy Properties with Image-Based Conditional Flow Matching
Mikaeel Yunus, John F. Wu, Benne W. Holwerda
Estimating physical properties of galaxies from wide-field surveys remains a central challenge in astrophysics. While spectroscopy provides precise measurements, it is observationa…
Broad-Line AGN at 3.5<z<6: The Black Hole Mass Function and a Connection with Little Red Dots
Anthony J. Taylor, Steven L. Finkelstein, Dale D. Kocevski +48
We present a sample of 50 H-alpha detected broad-line active galactic nuclei (BLAGN) at redshifts 3.5<z<6.8 using data from the CEERS and RUBIES surveys. We select these sources di…
The Abundance and Properties of Barred Galaxies out to 4 Using CEERS Data
Yuchen Guo, Shardha Jogee, Eden Wise +26
We present the first estimate of the observed fraction and properties of bars out to using CEERS NIRCam images. We analyze 1770 galaxies with $M_\star > 1…
The Complete Spitzer Survey of Stellar Structure in Galaxies (CSG)
P. M. Sánchez-Alarcón, H. Salo, J. H. Knapen +25
The Spitzer Survey of Stellar Structure in Galaxies (SG), together with its Early Type Galaxy (ETG) extension, stand as the most extensive dataset of deep, uniform mid-infrared…
The Rise of Faint, Red AGN at : A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields
Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro +54
We present a sample of 341 "little red dots" (LRDs) spanning the redshift range using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. Unlike past use of…
