Obscured active galactic nuclei from the ELAIS Deep X-ray Survey
The sources discovered in deep hard X-ray surveys with 2-8 keV fluxes of S2-8˜ 10-14 erg cm-2 s-1 make up the bulk of the X-ray background at these energies. Here we present detailed multiwavelength observations of three such sources from the European Large-Area ISO Survey Deep X-ray Survey. The observations include sensitive near-infrared
