31 Oct 2003 | | Subject: | astro-ph | | Affiliation: | Harvard-Smithsonian Center for Astrophysics | | Abstract: | We present an X-ray and optical analysis of a 2-8 keV flux limited (fx > 10e-14 erg s^-1 cm^-2) sample of 126 AGN detected in 16 Chandra fields. This work represents a small though significant subset of the Chandra Multiwavelength Project (ChaMP). We have chosen this limiting flux to have a reasonable degree of completeness (50%) in our optical spectroscopic identifications. The optical counterparts of these AGN are characterized as either broad emission line AGN (BLAGN; 67%), narrow emission line galaxies (NELG; 22%) or absorption line galaxies (ALG; 11%) without any evidence of an AGN signature. Based on their X-ray luminosity and spectral properties, we show that NELG and ALG are primarily the hosts of obscured AGN with an intrinsic absorbing column in the range of 10^21.5 | | Source: | arXiv, astro-ph/0310907 | | Services: | Forum | Review | PDF | Favorites | |
