The MIRI Early Obscured-AGN Wide Survey (MEOW): A Population of Hidden AGN at Revealed by JWST/MIRI Imaging

Gene C. K. Leung, Anna-Christina Eilers, Ryan Endsley +25

We present the MIRI Early Obscured-AGN Wide Survey (MEOW), a JWST/MIRI imaging survey designed to detect dust-obscured active galactic nuclei (AGN) across cosmic time, with a parti…

MEGA and SMILES Find Fewer Dusty Galaxies than Expected at Cosmic Noon

Bren E. Backhaus, Allison Kirkpatrick, Kurt Hamblin +10

We present infrared (IR) luminsosity functions (LFs) and resulting star formation rate densities using the JWST Mid-infrared Instrument (MIRI) observations from the MIRI EGS Galaxy…

AGNBoost: A Machine Learning Approach to AGN Identification with JWST/NIRCam+MIRI Colors and Photometry

Kurt Hamblin, Allison Kirkpatrick, Bren E. Backhaus +18

We present AGNBoost, a machine learning framework utilizing XGBoostLSS to identify AGN and estimate redshifts from JWST NIRCam and MIRI photometry. AGNBoost constructs 66 input fea…

The CEERS Photometric and Physical Parameter Catalog

Isa G. Cox, Jeyhan S. Kartaltepe, Micaela B. Bagley +35

We present the Cosmic Evolution Early Release Science Survey (CEERS) catalog, including space-based photometry, photometric redshifts, and physical parameters for more than 80,000…

MEGA: Spectrophotometric SED Fitting of Little Red Dots Detected in JWST MIRI

Kaila Ronayne, Casey Papovich, Allison Kirkpatrick +13

We analyze eight spectroscopically confirmed Little Red Dots (LRDs) at redshifts with JWST/NIRCam, NIRSpec, and MIRI data. The LRDs have red NIRCam colors, F150W-F444…

CEERS: Forging the First Dust Grains in the Universe? A Population of Galaxies with spectroscopically-derived Extremely Low Dust Attenuation (GELDA) at 4.0<z<11.4

Denis Burgarella, Véronique Buat, Patrice Theulé +35

We investigate the coevolution of metals and dust in 173 galaxies at using NIRSpec spectroscopy. Focusing on galaxies with extremely low dust attenuation, we explore t…
