内容記述 | Recent results from Suzaku observations of obscured active galactic nuclei (AGN) and implications for their evolution are presented. We utilize Suzaku data to measure broad-band spectra of obscured AGN selected by [OIII]lambda5007 optical emission lines or hard X-rays, and to constrain the structure of the nucleus. Spectra of obscured AGNs are well represented by a canonical model consisting of absorbed and unabsorbed power laws, a reflection continuum, an Fe-K line, and soft emission lines in most cases. We derive the distribution of absorption column densities for the [OIII] selected sample and find that about a half are Compton-thick, supporting earlier results with better quality of data. Some of hard X-ray selected obscured AGNs show very weak soft emission, which is presumed to be scattered by photoionized gas in the opening part of the absorber. The weakness of the scattered emission suggests that they are buried in a geometrically thick absorber. In order to explore such a new type of AGNs, we also present results on a new sample of obscured AGNs selected from the XMM-Newton serendipitous source catalogue and compare the geometry of obscuring matter and various fundamental parameters. | |||||
