A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn
Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42
We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…
Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
Optical Strong Line Ratios Cannot Distinguish Between Stellar Populations and Accreting Black Holes at High Ionization Parameters and Low Metallicities
Nikko J. Cleri, Grace M. Olivier, Bren E. Backhaus +24
High-redshift observations from JWST indicate that optical strong line ratios do not carry the same constraining power as they do at low redshifts. Critically, this prevents a sepa…
Spectroscopic confirmation of a dust-obscured, metal-rich dwarf galaxy at z~5
L. Bisigello, G. Gandolfi, A. Feltre +24
We present the first spectroscopic confirmation of a dust-obscured dwarf galaxy, CEERS-14821. The analysis is performed combining JWST NIRCam broad-band photometry and NIRSpec/PRIS…
The Cosmic Evolution Early Release Science Survey (CEERS)
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +96
We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates e…
