Probing black hole accretion tracks, scaling relations and radiative efficiencies from stacked X-ray active galactic nuclei
Francesco Shankar, David H. Weinberg, Christopher Marsden +25
The masses of supermassive black holes at the centres of local galaxies appear to be tightly correlated with the mass and velocity dispersions of their galactic hosts. However, the…
Constraining black hole-galaxy scaling relations from the large-scale clustering of Active Galactic Nuclei and implied mean radiative efficiency
Francesco Shankar, Viola Allevato, Mariangela Bernardi +11
A supermassive black hole has been found at the centre of nearly every galaxy observed with sufficient sensitivity. The masses of these black holes are observed to increase with ei…
BAT AGN Spectroscopic Survey -- XIII. The nature of the most luminous obscured AGN in the low-redshift universe
Rudolf E. Bär, Benny Trakhtenbrot, Kyuseok Oh +18
We present a multi wavelength analysis of 28 of the most luminous low-redshift narrow-line, ultra-hard X-ray selected active galactic nuclei (AGN) drawn from the 70 month Swift/BAT…
Optical characterization of WISE selected blazar candidates
Raniere de Menezes, Harold A. Peña-Herazo, Ezequiel J. Marchesini +8
Over the last decade more than five thousand gamma-ray sources were detected by the Large Area Telescope (LAT) on board Fermi Gamma-ray Space Telescope. Given the positional uncert…
Two new catalogs of blazar candidates in the WISE infrared sky
Raffaele D'Abrusco, Nuria Alvarez Crespo, Francesco Massaro +9
We present two catalogs of radio-loud candidate blazars whose WISE mid-infrared colors are selected to be consistent with the colors of confirmed gamma-ray emitting blazars. The fi…
Black hole scaling relations of active and quiescent galaxies: Addressing selection effects and constraining virial factors
Francesco Shankar, Mariangela Bernardi, Kayleigh Richardson +9
Local samples of quiescent galaxies with dynamically measured black hole masses (Mbh) may suffer from an angular resolution-related selection effect, which could bias the observed…
