ADC_Keywords: Galaxies, IR ; X-ray sources ; Active gal. nuclei Keywords: galaxies: evolution - quasars: general - X-rays: galaxies Abstract: We exploit deep combined observations with Spitzer and Chandra of the Spitzer Wide-Area Infrared Extragalactic Survey (SWIRE) in the ELAIS N1 region to investigate the nature of the faint X-ray and IR sources in common, to identify active galactic nucleus (AGN)/starburst diagnostics, and to study the sources of the X-ray and IR cosmic backgrounds (XRB and CIRB).

Note (1): Type from the Optical/IR SED, defined as follows: 1 = type-1 AGN; 2 = type-2 AGN; 3 = galaxy; 4 = early-type galaxy. Note (2): HR=(H-S)/(H+S) where H and S are the background-subtracted X-ray counts in the hard (2.0-8.0keV) and soft (0.5-2.0keV) bands, respectively.
