Abstract:
We present the first active galactic nuclei (AGN) census in a sample
of 61 galaxies selected at 70um, a wavelength which should strongly
favour the detection of star-forming systems. For the purpose of this
study, we take advantage of deep Chandra X-ray and Spitzer infrared
(3.6-160um) data, as well as optical spectroscopy and photometry from
the Deep Extragalactic Evolutionary Probe 2 (DEEP 2) survey for the
Extended Groth Strip (EGS) field, as part of the All-Wavelength
Extended Groth Strip International Survey. We investigate spectral
line diagnostics ([OIII]/H β and [NeIII]/[OII] ratios, Hδ
Balmer absorption line equivalent widths and the strength of the
4000Å break), X-ray luminosities and spectral energy distributions
(SEDs).
