BASS XXXIX: Swift-BAT AGN with changing-look optical spectra
Matthew J. Temple, Claudio Ricci, Michael J. Koss +13
Changing-look (CL) AGN are unique probes of accretion onto supermassive black holes (SMBHs), especially when simultaneous observations in complementary wavebands allow investigatio…
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. XXXVI. Constraining the Local Supermassive Black Hole - Halo Connection with BASS DR2 AGN
M. C. Powell, S. W. Allen, T. Caglar +12
We investigate the connection between supermassive black holes (SMBHs) and their host dark matter halos in the local universe using the clustering statistics and luminosity functio…
BASS XXXVII: The role of radiative feedback in the growth and obscuration properties of nearby supermassive black holes
C. Ricci, T. T. Ananna, M. J. Temple +22
We study the relation between obscuration and supermassive black hole (SMBH) growth using a large sample of hard X-ray selected Active Galactic Nuclei (AGN). We find a strong decre…
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…
BASS XXII: The BASS DR2 AGN Catalog and Data
Michael J. Koss, Claudio Ricci, Benny Trakhtenbrot +32
We present the AGN catalog and optical spectroscopy for the second data release of the Swift BAT AGN Spectroscopic Survey (BASS DR2). With this DR2 release we provide 1425 optical…
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 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)…
