Co-authors
Abstract	We can test the effects of strong gravity by studying the spectral and temporal behavior of some Seyfert nuclei. Specifically, the reflection components of X-rays emitted from the innermost edge of the disk very close to the central black hole can exhibit distinct features, such as a broad Fe line, hard X-ray hump near 10 keV, and large soft excess. Which of these components dominates depends on the property of the black hole and the environment very close to the hole - such as black hole's spin, the ionization state of the reflection material near the innermost edge of the disk, location of the coronal source emitting the illuminating primary X-rays, etc. We examined these properties by analyzing recent X-ray data of two Seyfert nuclei suitable for thess studies - CBS 126 and Mkn 766. Here we present our results.
