The impact of galaxy interactions on AGN activity in zCOSMOS
J. D. Silverman, P. Kampczyk, K. Jahnke +52
Close encounters between galaxies are expected to be a viable mechanism, as predicted by numerical simulations, by which accretion onto supermassive black holes can be initiated. T…
Dissecting Photometric redshift for Active Galactic Nuclei using XMM- and Chandra-COSMOS samples
M. Salvato, O. Ilbert, G. Hasinger +61
With this paper, we release accurate photometric redshifts for 1692 counterparts to Chandra sources in the central square degree of the COSMOS field. The availability of a large tr…
The bolometric output and host-galaxy properties of obscured AGN in the XMM-COSMOS survey
E. Lusso, A. Comastri, C. Vignali +15
We present a study of the multi-wavelength properties, from the mid-infrared to the hard X-rays, of a sample of 255 spectroscopically identified X-ray selected Type-2 AGN from the…
The Population of High Redshift AGNs in the Chandra COSMOS survey
F. Civano, M. Brusa, A. Comastri +19
We present the high redshift (3<z<5.3) 0.5-2 keV number counts and the 2-10 keV (rest frame) space density of X-ray selected AGNs detected in the Chandra COSMOS survey. The sample…
Accretion Rate and the Physical Nature of Unobscured Active Galaxies
Jonathan R. Trump, Christopher D. Impey, Brandon C. Kelly +15
We show how accretion rate governs the physical properties of a sample of unobscured broad-line, narrow-line, and lineless active galactic nuclei (AGNs). We avoid the systematic er…
Spectropolarimetric Evidence for Radiatively Inefficient Accretion in an Optically Dull Active Galaxy
Jonathan R. Trump, Tohru Nagao, Hiro Ikeda +9
We present Subaru/FOCAS spectropolarimetry of two active galaxies in the Cosmic Evolution Survey. These objects were selected to be optically dull, with the bright X-ray emission o…
