Implications of Broad [O III] 4364 and UV Line Emission in Two Little Red Dots at z ~ 7 - 8
Casey Papovich, Kaila Ronayne, Weida Hu +17
We present deep, NIRSpec G140M and G395M spectroscopy of Little Red Dots (LRDs) at z = 6.68 and z = 8.35. Both LRDs show broad Balmer and [O III] 4364 emission. The broad [O III…
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…
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…
The HST-Hyperion Survey: Environmental Imprints on the Stellar-Mass Function at z~2.5
Derek Sikorski, Ben Forrest, Brian C. Lemaux +19
Not all galaxies at Cosmic Noon evolve in the same way. It remains unclear how the local environment -- especially the extreme overdensities of protoclusters -- affects stellar mas…
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 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…
The HST-Hyperion Survey: Grism Observations of a Proto-Supercluster
Ben Forrest, Lu Shen, Brian C. Lemaux +19
We present first results and catalogs from the HST-Hyperion survey. This survey has collected 50 orbits of WFC3/F160W imaging and WFC3/G141 grism spectroscopy in the most overdense…
CEERS: Increasing Scatter along the Star-Forming Main Sequence Indicates Early Galaxies Form in Bursts
Justin W. Cole, Casey Papovich, Steven L. Finkelstein +29
We present the star-formation-rate -- stellar-mass (SFR-M) relation for galaxies in the CEERS survey at . We model the \jwst\ and \hst\ rest-UV and rest-op…
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 galaxies…
CEERS: Spatially Resolved UV and mid-IR Star Formation in Galaxies at 0.2 < z < 2.5: The Picture from the Hubble and James Webb Space Telescopes
Lu Shen, Casey Papovich, Guang Yang +38
We present the mid-IR (MIR) morphologies for 64 star-forming galaxies at with stellar mass using JWST MIRI observations from the Cosmic Evolut…
Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
Jorge A. Zavala, Veronique Buat, Caitlin M. Casey +121
Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-…
A Long Time Ago in a Galaxy Far, Far Away: A Candidate z ~ 12 Galaxy in Early JWST CEERS Imaging
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +117
We report the discovery of a candidate galaxy with a photo-z of z~12 in the first epoch of the JWST Cosmic Evolution Early Release Science (CEERS) Survey. Following conservative se…
