A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling
Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33
Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…
Properties of black holes in non-linear electrodynamics
Lewis Croney, Ruth Gregory, Ansh Gupta +1
We investigate the properties of charged black hole geometries in nonlinear electrodynamics. We focus on the recently reported analytic charged black hole solutions to illustrate t…
Significant Evidence of an AGN Contribution in GHZ2 at z = 12.34
Oscar A. Chavez Ortiz, Steven L. Finkelstein, Adele Plat +19
GHZ2 is among the highest-redshift galaxies discovered to date, exhibiting a spectrum rich with prominent emission lines in the rest-frame ultraviolet (UV) and optical. These featu…
CAPERS-LRD-z9: A Gas Enshrouded Little Red Dot Hosting a Broad-line AGN at z=9.288
Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski +49
We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam pho…
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…
