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…
First Detection of an Over-Massive Black Hole Galaxy UHZ1: Evidence for Heavy Black Hole Seed Formation from Direct Collapse
Priyamvada Natarajan, Fabio Pacucci, Angelo Ricarte +3
The recent Chandra-JWST discovery of a quasar in the z = 10.1 galaxy UHZ1 reveals that accreting supermassive black holes (SMBHs) were already in place 470 million years after the…
A quasar-based supermassive black hole binary population model: implications for the gravitational-wave background
J. Andrew Casey-Clyde, Chiara M. F. Mingarelli, Jenny E. Greene +3
The nanohertz gravitational wave background (GWB) is believed to be dominated by GW emission from supermassive black hole binaries (SMBHBs). Observations of several dual active gal…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The first archetypal Quasar in the feedback phase discovered by eROSITA
M. Brusa, T. Urrutia, Y. Toba +18
Theoretical models of galaxy-AGN co-evolution ascribe an important role for the feedback process to a short, luminous, obscured, and dust-enshrouded phase during which the accretio…
The Chandra Deep Wide-Field Survey: A New Chandra Legacy Survey in the Boötes Field I. X-ray Point Source Catalog, Number Counts and Multi-Wavelength Counterparts
A. Masini, R. C. Hickox, C. M. Carroll +30
We present a new, ambitious survey performed with the Chandra X-ray Observatory of the 9.3 deg Boötes field of the NOAO Deep Wide-Field Survey. The wide field probes a statisti…
A Second Look at 12 Candidate Dual AGNs using
Adi Foord, Kayhan Gültekin, Rebecca Nevin +5
We present an analysis of 12 optically selected dual AGN candidates at . Each candidate was originally identified via double-peaked [O III] 5007 emission lines, and ha…
