BASS XXX: Distribution Functions of DR2 Eddington-ratios, Black Hole Masses, and X-ray Luminosities
Tonima Tasnim Ananna, Anna K. Weigel, Benny Trakhtenbrot +19
We determine the low-redshift X-ray luminosity function (XLF), active black hole mass function (BHMF), and Eddington-ratio distribution function (ERDF) for both unobscured (Type 1)…
Probing the circumnuclear environment of NGC1275 with High-Resolution X-ray spectroscopy
Christopher S. Reynolds, Robyn N. Smith, Andrew C. Fabian +6
NGC1275 is the Brightest Cluster Galaxy (BCG) in the Perseus cluster and hosts the active galactic nucleus (AGN) that is heating the central 100\,kpc of the intracluster medium (IC…
Forward Modeling Populations of Flares from Tidal Disruptions of Stars by Super-massive Black Holes
Nathaniel Roth, Sjoert van Velzen, S. Bradley Cenko +1
Detections of the tidal disruption flares (TDFs) of stars by supermassive black holes (SMBHs) are rapidly accumulating as optical surveys improve. These detections may provide cons…
The BAT AGN Spectroscopic Survey -- XVIII. Searching for Supermassive Black Hole Binaries in the X-rays
Tingting Liu, Michael Koss, Laura Blecha +15
Theory predicts that a supermassive black hole binary (SMBHB) could be observed as a luminous active galactic nucleus (AGN) that periodically varies on the order of its orbital tim…
The nature of the broadband X-ray variability in the dwarf Seyfert galaxy NGC 4395
E. S. Kammoun, E. Nardini, A. Zoghbi +14
We present a flux-resolved X-ray analysis of the dwarf Seyfert 1.8 galaxy NGC 4395, based on three archival and one archival observations. The source is known…
X-Ray Spectrum of RBS 315: Absorption or Intrinsic Curvature
Sivan Ben Haim, Ehud Behar, Richard F. Mushotzky
X-ray absorption of high-redshift quasars is enigmatic, because it remains unclear where in the universe the absorbing gas is. If absorption occurs near the high-z host, it could h…
