According to the latest versions of synthesis modeling of the Cosmic X-ray Background, Compton-thick AGN should represent ~50 % of the total absorbed AGN population.

Abstract
According to the latest versions of synthesis modeling of the Cosmic X-ray Background, Compton-thick AGN should represent ~50 % of the total absorbed AGN population. However, despite their importance in the cosmological context, only a few dozens of Compton-thick AGN have been found and studied so far. We will briefly review this topic and discuss the improvement in this field offered by the Simbol-X mission with its leap in sensitivity (E>10 keV) of more than a factor 500 with respect to previous X-ray missions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
