Descripción
We present ultraviolet to mid-infrared spectral energy distributions for
a sample of 116 AGN in the Extended Groth Strip selected both in the
X-rays and mid-infrared (96 with single detections and 20 with multiple
optical counterparts). A complete set of different AGN types and
starburst galaxy templates are used to fit the objects spectral energy
distributions. Five main template groups are considered, namely,
Starburst-dominated AGN (24 % of the sample), Starburst-contaminated AGN
(7 %), Type-1 AGN (21 %), Type-2 AGN (24 %), and Normal galaxy hosting
AGN (24 %). Type-2 AGN and Normal galaxy hosting AGN sources are
concentrated at low redshifts, whereas Starburst-dominated AGN and
Type-1 AGN show a larger span. Correlations between hard/soft X-ray and
ultraviolet, optical and infrared luminosities, respectively, are
reported, showing a noticeable improvement when only Type-1 AGN-fitted
objects are considered. For the rest of the populations, these
correlations get worse when we consider the soft X-ray instead of the
hard X-rays, probably due to the higher obscuration that affects the
objects in these populations. The percentage of Starburst-dominated AGN
objects amongst the subset of objects with double detections increases
up to 48%.
