XMM-Newton and NuSTAR Observations of an Optically Quiescent Quasar
Claire Greenwell, Poshak Gandhi, George Lansbury +3
Optically quiescent quasars (OQQs) represent a recently systematised class of infrared-luminous active galactic nuclei (AGN) which have galaxy-like optical continua. They may repre…
A New Emulated Monte Carlo Radiative Transfer Disk-Wind Model: X-Ray Accretion Disk-wind Emulator -- XRADE
G. A. Matzeu, M. Lieu, M. T. Costa +14
We present a new X-Ray Accretion Disk-wind Emulator (\textsc{xrade}) based on the 2.5D Monte Carlo radiative transfer code which provides a physically-motivated, self-consistent tr…
Resolving the cosmic X-ray background with a next-generation high-energy X-ray observatory
R. C. Hickox, F. Civano, D. R. Ballantyne +16
The cosmic X-ray background (CXB), which peaks at an energy of ~30 keV, is produced primarily by emission from accreting supermassive black holes (SMBHs). The CXB therefore serves…
A New Compton-thick AGN in our Cosmic Backyard: Unveiling the Buried Nucleus in NGC 1448 with NuSTAR
A. Annuar, D. M. Alexander, P. Gandhi +22
NGC 1448 is one of the nearest luminous galaxies ( 10) to ours ( 0.00390), and yet the active galactic nucleus (AGN) it hosts was only recent…
Broadband X-ray spectral analysis of the Seyfert 1 galaxy GRS 1734-292
A. Tortosa, A. Marinucci, G. Matt +14
We discuss the broadband X-ray spectrum of GRS 1734-292 obtained from non-simultaneous XMM-Newton and NuSTAR observations, performed in 2009 and 2014, respectively. GRS1734-292 is…
Chandra Reveals Heavy Obscuration and Circumnuclear Star Formation in Seyfert 2 Galaxy NGC 4968
Stephanie M. LaMassa, Tahir Yaqoob, N. A. Levenson +6
We present the Chandra imaging and spectral analysis of NGC 4968, a nearby (z = 0.00986) Seyfert 2 galaxy. We discover extended (1 kpc) X-ray emission in the soft band (0.5 -…
