【 摘 要 】

The energy driving a quasar or active galactic nucleus (AGN) is thought to come from the accretion of gas on to a supermassive black hole at the center of the host galaxy. Evidence for this has been hard to find, but the extremely broad iron line observed in the X-ray spectrum of one particular AGN (the Seyfert galaxy known as MCG-6-30-15) may well be the calling card of a supermassive black hole. A new model-independent approach to analyzing these intriguing X-ray emissions extracts more information about the black hole within--including the position of the inner edge of the accretion disk and the rate at which the black hole is rotating.
