BAT AGN Spectroscopic Survey--VIII. Type 1 AGN With Massive Absorbing Columns
T. Taro Shimizu, Richard I. Davies, Michael Koss +12
We explore the relationship between X-ray absorption and optical obscuration within the BAT AGN Spectroscopic Survey (BASS) which has been collecting and analyzing the optical and…
xCOLD GASS: the complete IRAM-30m legacy survey of molecular gas for galaxy evolution studies
Amélie Saintonge, Barbara Catinella, Linda J. Tacconi +18
We introduce xCOLD GASS, a legacy survey providing a census of molecular gas in the local Universe. Building upon the original COLD GASS survey, we present here the full sample of…
The close environments of accreting massive black holes are shaped by radiative feedback
Claudio Ricci, Benny Trakhtenbrot, Michael J. Koss +13
The large majority of the accreting supermassive black holes in the Universe are obscured by large columns of gas and dust. The location and evolution of this obscuring material ha…
NuSTAR Resolves the First Dual AGN above 10 keV in SWIFT J2028.5+2543
Michael J. Koss, Ana Glidden, Mislav Balokovic +19
We have discovered heavy obscuration in the dual active galactic nucleus (AGN) in the Swift/Burst Alert Telescope (BAT) source SWIFT J2028.5+2543 using Nuclear Spectroscopic Telesc…
The NuSTAR Serendipitous Survey: Hunting for The Most Extreme Obscured AGN at >10 keV
G. B. Lansbury, D. M. Alexander, J. Aird +27
We identify sources with extremely hard X-ray spectra (i.e., with photon indices of Gamma<0.6 in the 13 sq. deg. NuSTAR serendipitous survey, to search for the most highly obscured…
BAT AGN Spectroscopic Survey I: Spectral Measurements, Derived Quantities, and AGN Demographics
Michael Koss, Benny Trakhtenbrot, Claudio Ricci +20
We present the first catalog and data release of the Swift-BAT AGN Spectroscopic Survey (BASS). We analyze optical spectra of the majority of AGN (77%, 641/836) detected based on t…
