NuSTAR Uncovers an Extremely Local Compton-thick AGN in NGC 4968
Stephanie M. LaMassa, Tahir Yaqoob, Peter G. Boorman +5
We present the analysis of Chandra and NuSTAR spectra of NGC 4968, a local (D44 Mpc) 12m-selected Seyfert 2 galaxy, enshrouded within Compton-thick layers of obscuring gas…
Broad Band X-ray Constraints on the Accreting Black Hole in Quasar 4C 74.26
P. Tzanavaris, T. Yaqoob, S. LaMassa +2
X-ray data for quasar 4C 74.26 have previously been modeled with a broad Fe K emission line and reflection continuum originating in the inner part of the accretion disk around t…
Photometric redshifts for X-ray-selected active galactic nuclei in the eROSITA era
M. Brescia, M. Salvato, S. Cavuoti +5
With the launch of eROSITA (extended Roentgen Survey with an Imaging Telescope Array), successfully occurred on 2019 July 13, we are facing the challenge of computing reliable phot…
The Accretion History of AGN: A Newly Defined Population of Cold Quasars
Allison Kirkpatrick, C. Megan Urry, Jason Brewster +15
Quasars are the most luminous of active galactic nuclei (AGN), and are perhaps responsible for quenching star formation in their hosts. The Stripe 82X catalog covers 31.3 deg o…
Cosmic evolution of supermassive black holes: A view into the next two decades
Francesca Civano, Nico Cappelluti, Ryan Hickox +38
The discoveries made over the past 20 years by Chandra and XMM-Newton surveys in conjunction with multiwavelength imaging and spectroscopic data available in the same fields have s…
SDSS-IV eBOSS Spectroscopy of X-ray and WISE AGN in Stripe 82X: Overview of the Demographics of X-ray and Mid-Infrared Selected Active Galactic Nuclei
Stephanie M. LaMassa, Antonis Georgakakis, M. Vivek +5
We report the results of a Sloan Digital Sky Survey-IV eBOSS program to target X-ray sources and mid-infrared-selected WISE AGN candidates in a 36.8 deg region of Stripe 82. Ab…
