Abstract:
We report the final optical identifications of the medium-depth
(∼60ks), contiguous (2deg2) XMM-Newton survey of the COSMOS field.
XMM-Newton has detected ∼1800 X-ray sources down to limiting fluxes of
∼5x10-16, ∼3x10-15, and ∼7x10-15erg/cm2/s in the 0.5-2keV,
2-10keV, and 5-10keV bands, respectively (∼1x10-15, ∼6x10-15, and
∼1x10-14erg/cm2/s, in the three bands, respectively, over 50% of
the area). The work is complemented by an extensive collection of
multiwavelength data from 24um to UV, available from the COSMOS
survey, for each of the X-ray sources, including spectroscopic
redshifts for ≳50% of the sample, and high-quality photometric
redshifts for the rest. The XMM and multiwavelength flux limits are
well matched: 1760 (98%) of the X-ray sources have optical
counterparts, 1711 (∼95%) have IRAC counterparts, and 1394 (∼78%) have
MIPS 24um detections. Spectroscopically identified obscured and
unobscured AGNs, as well as normal and star-forming galaxies, present
well-defined optical and infrared properties. We devised a robust
method to identify a sample of ∼150 high-redshift (z>1), obscured AGN
candidates for which optical spectroscopy is not available.
