Abstract:
We present a study of the X-ray to optical properties of a sample of
545 X-ray selected Type 1 AGN, from the XMM-COSMOS survey, over a wide
range of redshifts (0.04<z<4.25) and X-ray luminosities
(40.6≤LogL[2-10]keV≤45.3). About 60% of them are spectroscopically
identified Type 1 AGN, while the others have a reliable photometric
redshift and are classified as Type 1 AGN on the basis of their
multi-band Spectral Energy Distributions. We discuss the relationship
between UV and X-ray luminosity, as parameterized by the alphaox
spectral slope, and its dependence on redshift and luminosity.
Description:
Optical and X-ray properties for 545 Type 1 AGN in XMM-COSMOS are
presented. For each source, X-ray ID, spectroscopic redshift,
photometric redshift, upper error on the photometric redshift, lower
error on the photometric redshift, logarithm of the monochromatic
luminosity al 2500Å, logarithm of the monochromatic luminosity at
2keV, alphaox, logarithm of the 2-10keV luminosity, logarithm of the
bolometric luminosity in solar units, bolometric correction,
photometric classification, logarithm of the Eddington ratio,
logarithm of the black hole mass in 109 solar masses, flag for the
2-10keV detection (flag=1 [343 entries] means a detection in the
2-10keV band, while flag=0 is for 2-10keV upper limits).
