Stripe 82X Data Release 3: Multiwavelength Catalog with New Spectroscopic Redshifts and Black Hole Masses
Stephanie M. LaMassa, Alessandro Peca, C. Megan Urry +10
We present the third catalog release of the wide-area (31.3 deg) Stripe 82 X-ray survey. This catalog combines previously published X-ray source properties with multiwavelength…
The High Energy X-ray Probe (HEX-P): Bringing the Cosmic X-ray Background into Focus
Francesca Civano, Xiurui Zhao, Peter Boorman +29
Since the discovery of the cosmic X-ray background (CXB), astronomers have strived to understand the accreting supermassive black holes (SMBHs) contributing to its peak in the 10-4…
The High Energy X-ray Probe (HEX-P): The Circum-nuclear Environment of Growing Supermassive Black Holes
P. G. Boorman, N. Torres-Albà, A. Annuar +32
Ever since the discovery of the first Active Galactic Nuclei (AGN), substantial observational and theoretical effort has been invested into understanding how massive black holes ha…
NGC 4388: A Test Case for Relativistic Disk Reflection and Fe K Fluorescence Features
Tahir Yaqoob, P. Tzanavaris, S. LaMassa
We present a new analysis of the Suzaku X-ray spectrum of the Compton-thin Seyfert 2 galaxy NGC 4388. The spectrum above 2 keV can be described by a remarkably simple and rat…
The Complex X-ray Obscuration Environment in the Radio Loud Type 2 Quasar 3C 223
Stephanie M. LaMassa, Tahir Yaqoob, Panayiotis Tzanavaris +4
3C 223 is a radio loud, Type 2 quasar at with an intriguing XMM-Newton spectrum that implicated it as a rare, Compton-thick ( cm$^…
Are Compton-thin AGNs Globally Compton Thin?
P. Tzanavaris, T. Yaqoob, S. LaMassa +2
We select eight nearby AGNs which, based on previous work, appear to be Compton-thin in the line of sight. We model with MYTORUS their broadband X-ray spectra from 20 individual ob…
