XMM-Newton Observations of MCG-6-30-15

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 Fe Kαline in this source is found to be extremely broad.Modeling the line using a line emissivity I(r)∝r^-β we find β>3.This indicates that most line emission comes from the innermost regions around the central black hole.The emissivity coefficient is steeper than expected for standardmodels for the Fe Kαemission.This steep emission might be due to energy extraction from a rotating black hole.
