Abstract:
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 errors plaguing previous
studies of AGN accretion rates by using accurate intrinsic accretion
luminosities (Lint) from well-sampled multiwavelength spectral energy
distributions from the Cosmic Evolution Survey, and accurate black
hole masses derived from virial scaling relations (for broad-line
AGNs) or host-AGN relations (for narrow-line and lineless AGNs).
Description:
We select a sample of 348 AGNs from the COSMOS (Scoville et al.
2007ApJS..172...38S 2007ApJS..172...38S) field, which is based on the 1.7deg2 Hubble
Space Telescope (HST)/Advanced Camera for Surveys (ACS) mosaic. These
AGNs have multiwavelength data in the form of Spitzer/IRAC, HST/ACS,
Subaru/Suprime-Cam, GALEX, XMM-Newton, and Chandra observations. The
sample is selected from the parent catalog of 1651 XMM-COSMOS point
sources with optical counterparts (Brusa et al. 2010, Cat. J/ApJ/716/348).
