Breaking the rules at 0.45: the rebel case of RBS 1055
A. Marinucci, G. Vietri, E. Piconcelli +5
We report on a long (250 ks) NuSTAR observation of the bright quasar RBS 1055 performed in March 2021, and archival XMM-Newton pointings (185 ks) taken in July 2014. An optical spe…
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 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…
NuSTAR Observations of Intrinsically X-ray Weak Quasar Candidates: An Obscuration-Only Scenario
Chaojun Wang, B. Luo, W. N. Brandt +6
We utilize recent NuSTAR observations (co-added depth -120 ks) of PG , PG , and PHL 1811 to constrain their hard X-ray ( keV) weakness and…
XMM-Newton and NuSTAR Observations of an Optically Quiescent Quasar
Claire Greenwell, Poshak Gandhi, George Lansbury +3
Optically quiescent quasars (OQQs) represent a recently systematised class of infrared-luminous active galactic nuclei (AGN) which have galaxy-like optical continua. They may repre…
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…
