First Results from the JWST Early Release Science Program Q3D: AGN Photoionization and Shock Ionization in a Red Quasar at
Swetha Sankar, Nadia L. Zakamska, David S. N. Rupke +12
Red quasars, often associated with powerful [O III] outflows on both galactic and circumgalactic scales, may play a pivotal role in galaxy evolution and black hole feedback. In thi…
UNCOVERing the High-redshift AGN Population among Extreme UV Line Emitters
Helena Treiber, Jenny Greene, John R. Weaver +23
JWST has revealed diverse new populations of high-redshift () AGN and extreme star-forming galaxies that challenge current models. In this paper, we use rest-frame UV em…
Quasars can Signpost Supermassive Black Hole Binaries
J. Andrew Casey-Clyde, Chiara M. F. Mingarelli, Jenny E. Greene +3
Supermassive black holes (SMBHs) are found in the centers of massive galaxies, and galaxy mergers should eventually lead to SMBH mergers. Quasar activity has long been associated w…
UNCOVER: 404 Error -- Models Not Found for the Triply Imaged Little Red Dot A2744-QSO1
Yilun Ma, Jenny E. Greene, David J. Setton +20
JWST has revealed an abundance of compact, red objects at dubbed "little red dots" (LRDs), whose SEDs display a faint blue UV continuum followed by a steep rise in th…
RUBIES: JWST/NIRSpec Confirmation of an Infrared-luminous, Broad-line Little Red Dot with an Ionized Outflow
Bingjie Wang, Anna de Graaff, Rebecca L. Davies +22
The JWST discovery of ``little red dots'' (LRDs) is reshaping our picture of the early Universe, yet the physical mechanisms driving their compact size and UV-optical colors remain…
UNCOVERing the contribution of black holes to reionization in the JWST era
Pratika Dayal, Marta Volonteri, Jenny E. Greene +13
With its sensitivity in the rest-frame optical, the James Webb Space Telescope (JWST) has uncovered active galactic nuclei (AGN), comprising both intrinsically faint and heavily re…
