BAT AGN Spectroscopic Survey - V. X-ray properties of the Swift/BAT 70-month AGN catalog
Claudio Ricci, Benny Trakhtenbrot, Michael J. Koss +18
Hard X-ray ( keV) observations of Active Galactic Nuclei (AGN) can shed light on some of the most obscured episodes of accretion onto supermassive black holes. The 70-mont…
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…
Determining the radio AGN contribution to the radio-FIR correlation using the black hole fundamental plane relation
O. Ivy Wong, M. J. Koss, K. Schawinski +5
We investigate the 1.4 GHz radio properties of 92 nearby (z<0.05) ultra hard X-ray selected Active Galactic Nuclei (AGN) from the Swift Burst Alert Telescope (BAT) sample. Through…
Active galactic nuclei flicker: an observational estimate of the duration of black hole growth phases of ~1e5 years
Kevin Schawinski, Michael Koss, Simon Berney +1
We present an observational constraint for the typical active galactic nucleus (AGN) phase lifetime. The argument is based on the time lag between an AGN central engine switching o…
