摘      要：We report on XMM Newton guaranteed time observations of the Seyfert galaxy MCG 6 30 15. Confirming earlier results from ASCA, BeppoSAX , and RXTE, the fluorescent FeKα line in this source is found to be extremely broad. Modeling the line using a line emissivity I(r)∝r -β we find β*** indicates that most line emission comes from the innermost regions around the central black hole. The emissivity coefficient is steeper than expected for standard models for the Fe Kα emission. This steep emission might be due to energy extraction from a rotating black hole.
