| Abstract: |
Active Galactic Nuclei (AGN) are now believed to be powered by supermassive black holes. Various satellite missions observed many of these objects and their spectra have been well studied. They can consist of various components, and there is a possibility that one of these components, ionized relativistic reflection (IRR), is emitted from the innermost accretion disk very close to the central blackhole. This emission can produce several interesting distinct spectral features which include not only broaded Fe lines but also prominent hard X-ray hump and blurred reflection features in X-ray soft excess regions. We are trying to test strong gravity with both observations of AGN by various satellite missions such as Suzaku, NuStar and XMM-Newton, and with comparison of the observed data thus obtained with the prediction by the IRR theories. |
