The Detection of a Compact Radio Feature in a Seyfert Galaxy After an Accretion Rate Change
K. É. Gabányi, K. Smith, S. Frey +3
X-ray binaries are known to show state transitions related to accretion rate changes which are often accompanied with dramatic changes in the jet emission. However, it is not clear…
UGC 4211: A Confirmed Dual Active Galactic Nucleus in the Local Universe at 230 pc Nuclear Separation
Michael J. Koss, Ezequiel Treister, Darshan Kakkad +23
We present multi-wavelength high-spatial resolution (~0.1'', 70 pc) observations of UGC 4211 at z=0.03474, a late-stage major galaxy merger at the closest nuclear separation yet fo…
BASS XXXII: Studying the Nuclear Mm-wave Continuum Emission of AGNs with ALMA at Scales 100-200 pc
Taiki Kawamuro, Claudio Ricci, Masatoshi Imanishi +25
To understand the origin of nuclear ( 100 pc) millimeter-wave (mm-wave) continuum emission in active galactic nuclei (AGNs), we systematically analyzed sub-arcsec resolut…
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 XXIX: The near-infrared view of the BLR: the effects of obscuration in BLR characterisation
Ricci F., Treister E., Bauer F. E. +24
Virial black hole mass () determination directly involves knowing the broad line region (BLR) clouds velocity distribution, their distance from the central supermassive bla…

J. Drew Hogg, Laura Blecha, Christopher S. Reynolds +2
We present a spectroscopic and imaging study of an abnormal active galactic nucleus (AGN), 2MASX J00423991+3017515. This AGN is newly identified in the hard X-rays by the Swift BAT…
