Abstract:
We have employed a reliable technique of classification of active
galactic nuclei (AGNs) based on the fit of well sampled spectral
energy distributions (SEDs) with a complete set of AGN and starburst
galaxy templates. We have compiled UV, optical, and IR data for a
sample of 116 AGNs originally selected for their X-ray and mid-IR
emissions (96 with single detections and 20 with double optical
counterparts). This is the most complete compilation of
multiwavelength data for such a large sample of AGN in the Extended
Groth Strip. Through these SEDs, we are able to obtain highly reliable
photometric redshifts and to distinguish between pure and
host-dominated AGNs.
