The circumnuclear material around AGN feed the central super massive black hole and produce intense X-ray emission. The surrounding material will reprocess the intrinsic X-ray emission and leave unique features on the observed X-ray emission. I will present an overview of recent progress on the "torus" around AGN and show how one can probe the circumnuclear material of AGN with observed X-ray signatures. Similar processes are also happening around high mass X-ray binaries, but with more plentiful phenomena due to the strong magnetic field of neutron stars. I will report some recent findings on their circumnuclear material and some indications of the existence of tidal outflow in high mass X-ray binaries, which may significantly shorten their evolution time to double compact stars. |
