Active Galactic Nuclei from HeII: a more complete census of AGN in SDSS galaxies yields a new population of low-luminosity AGN in highly star-forming galaxies
Rudolf Bär, Anna K. Weigel, Lia F. Sartori +3
In order to perform a more complete census of active galactic nuclei (AGN) in the local Universe, we investigate the use of the HeII~ emission line diagnostic diagram by Shi…
The Complete Infrared View of Active Galactic Nuclei from the 70-month Swift/BAT Catalog
Kohei Ichikawa, Claudio Ricci, Yoshihiro Ueda +5
We systematically investigate the near- (NIR) to far-infrared (FIR) photometric properties of a nearly complete sample of local active galactic nuclei (AGN) detected in the Swift/B…
The Role of Host Galaxy for the Environmental Dependence of Active Nuclei in Local Galaxies
R. I. Davies, E. K. S. Hicks, P. Erwin +22
We discuss the environment of local hard X-ray selected active galaxies, with reference to two independent group catalogues. We find that the fraction of these AGN in S0 host galax…
BAT AGN Spectroscopic Survey-III. An observed link between AGN Eddington ratio and narrow emission line ratios
Kyuseok Oh, Kevin Schawinski, Michael Koss +14
We investigate the observed relationship between black hole mass (), bolometric luminosity (), and Eddington ratio () with optical emission li…
Constraints on the Broad Line Region Properties and Extinction in Local Seyferts
Allan Schnorr-Müller, R. I. Davies, K. T. Korista +22
We use high spectral resolution (R > 8000) data covering 3800-13000Å to study the physical conditions of the broad line region (BLR) of nine nearby Seyfert 1 galaxies. Up to six br…
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…
