We present results from a spectral analysis of a sample of 34 high-redshift (z > 3) X-ray selected AGN in the 4 Ms Chandra Deep Field South, the deepest X-ray survey to date. The intrinsic column density distribution, corrected for observational bi- ases using spectral simulations, and the source number counts down to flux F0.5−2keV∼ 4 × 10−17 erg s−1 cm−2 are compared with the expectations from X-ray background synthesis models. All the results are presented and discussed in Vito et al. (2013).

Abstract
We present results from a spectral analysis of a sample of 34 high-redshift (z > 3) X-ray selected AGN in the 4 Ms Chandra Deep Field South, the deepest X-ray survey to date. The intrinsic column density distribution, corrected for observational bi- ases using spectral simulations, and the source number counts down to flux F0.5−2keV∼ 4 × 10−17 erg s−1 cm−2 are compared with the expectations from X-ray background synthesis models. All the results are presented and discussed in Vito et al. (2013).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
