Beyond the Monsters: A More Complete Census of Black Hole Activity at Cosmic Dawn

Madisyn Brooks, Jonathan R. Trump, Raymond C. Simons +19

JWST has revealed an abundance of low-luminosity active galactic nuclei (AGN) at high redshifts (), pushing the limits of black hole (BH) science in the early Universe. Resu…

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…

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…

CAPERS Observations of Two UV-Bright Galaxies at z>10. More Evidence for Bursting Star Formation in the Early Universe

Vasily Kokorev, Óscar A. Chávez Ortiz, Anthony J. Taylor +38

We present the first results from the CAPERS survey, utilizing PRISM observations with the JWST/NIRSpec MSA in the PRIMER-UDS field. With just 14 % of the total planned data volume…

Extended Enriched Gas in a Multi-Galaxy Merger at Redshift 6.7

Weida Hu, Casey Papovich, Lu Shen +5

Recent JWST observations have uncovered high-redshift galaxies characterized by multiple star-forming clumps, many of which appear to be undergoing mergers. Such mergers, especiall…

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…
