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).

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.
