Descripción
We present results of the X-ray spectral analysis of the ˜370 ksec deep survey obtained with XMM-Newton on the Chandra Deep Field South (CDFS). Using sample of 127 sources with redshift identifications and with a raw count limit of 100 (pn detector) we explored both the physical properties of individual sources, and the general properties of two AGN classes. The corresponding flux limits in the (0.5-2) and (2-10) keV bands are 1 × 10-16 and 9 × 10-16 erg cm-2 s-1, respectively. The average photon index is Γ ˜1.9 and Γ ˜1.8 for type-1 AGN and type-2 AGN, respectively. Although the properties of the spectra of more that 90% of AGN are in good agreement with the unified model, a fraction of ‘atypical’ objects (absorbed type-1 and unabsorbed type-2 AGN) was detected.
