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…
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…
MEGA Mass Assembly with JWST: The MIRI EGS Galaxy and AGN Survey
Bren E. Backhaus, Allison Kirkpatrick, Guang Yang +8
We present the MIRI EGS Galaxy and AGN (MEGA) survey, a four band MIRI survey with 25 pointing in the Extended Groth Strip (EGS) extragalactic field. Three of the pointings utilize…
