BAT AGN Spectroscopic Survey-XX: Molecular Gas in Nearby Hard X-ray Selected AGN Galaxies
Michael J. Koss, Benjamin Strittmatter, Isabella Lamperti +23
We present the host galaxy molecular gas properties of a sample of 213 nearby (0.01<z< 0.05) hard X-ray selected AGN galaxies, drawn from the 70-month catalog of Swift-BAT, with 20…
The destruction and recreation of the X-ray corona in a changing-look Active Galactic Nucleus
C. Ricci, E. Kara, M. Loewenstein +16
We present the drastic transformation of the X-ray properties of the active galactic nucleus 1ES 1927+654, following a changing-look event. After the optical/UV outburst the power-…
ALMA Observations of Quasar Host Galaxies at
Nathen H. Nguyen, Paulina Lira, Benny Trakhtenbrot +4
We present ALMA band-7 data of the [CII] emission line and underlying far-infrared (FIR) continuum for twelve luminous quasars at , powered…
What do observations tell us about the highest-redshift supermassive black holes?
Benny Trakhtenbrot
I review the current understanding of some key properties of the earliest growing supermassive black holes (SMBHs), as determined from the most up-to-date observations of z>=5 quas…
BAT AGN Spectroscopic Survey -- XV: The High Frequency Radio Cores of Ultra-hard X-ray Selected AGN
Krista Lynne Smith, Richard F. Mushotzky, Michael Koss +14
We have conducted 22 GHz radio imaging at 1" resolution of 100 low-redshift AGN selected at 14-195 keV by the Swift-BAT. We find a radio core detection fraction of 96%, much higher…
