Dissecting AGN Spectral Energy Distributions: Obscuration and Host Contribution

摘要

The X-ray-infrared spectral energy distributions (SEDs) of a sam-ple of X-ray selected AGN at z=0.2-3 are modeled with a nuclear and host com-ponent in order to determine the importance of host type, nuclear obscuration, and AGN intrinsic SED in sources of different type and luminosity. Overall, there is a good correspondence between optical obscuration and X-ray absorp-tion. The AGN is X-ray absorbed in type 2 AGN and unabsorbed in type 1 AGN, as expected. We find two types of intrinsic AGN SEDs with different X-ray/mid-infrared luminosity ratios independently of the AGN luminosity and obscuration.
