Probing the Structure and Evolution of BASS AGN through Eddington Ratios
Tonima Tasnim Ananna, C. Megan Urry, Claudio Ricci +23
We constrain the intrinsic Eddington ratio (\lamEdd ) distribution function for local AGN in bins of low and high obscuration (log NH <= 22 and 22 < log NH < 25), using the Swift-B…
BASS XXVI: DR2 Host Galaxy Stellar Velocity Dispersions
Michael J. Koss, Benny Trakhtenbrot, Claudio Ricci +18
We present new central stellar velocity dispersions for 484 Sy 1.9 and Sy 2 from the second data release of the Swift/BAT AGN Spectroscopic Survey (BASS DR2). This constitutes the…
BAT AGN Spectroscopic Survey XXI: The Data Release 2 Overview
Michael J. Koss, Benny Trakhtenbrot, Claudio Ricci +24
The BAT AGN Spectroscopic Survey (BASS) is designed to provide a highly complete census of the key physical parameters of supermassive black holes (SMBHs) that power local active g…
BASS XXV: DR2 Broad-line Based Black Hole Mass Estimates and Biases from Obscuration
Julian E. Mejıa-Restrepo, Benny Trakhtenbrot, Michael J. Koss +26
We present measurements of broad emission lines and virial estimates of supermassive black hole masses () for a large sample of ultra-hard X-ray selected active galactic nu…
BASS XXIV: The BASS DR2 Spectroscopic Line Measurements and AGN Demographics
Kyuseok Oh, Michael J. Koss, Yoshihiro Ueda +17
We present the second catalog and data release of optical spectral line measurements and AGN demographics of the BAT AGN Spectroscopic Survey, which focuses on the of Swift-BAT har…
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)…
