Abstract XMM and Chandra data have recently revealed complex and exciting behavior in theFe K-band of Seyfert-type AGN. These include rapid variations in line energy,characteristic of gas orbiting a central black hole, and a tight correlation ofthe ionized line component with flux. These strengthen the assertion asignificant fraction of Fe Ka emission is from the accretion disk. We havesearched the XMM archive for AGN where line emission appears dominated by theinner disk. Mkn 205 is the best target for continuing Fe Ka studies in XMM cycle5, and we propose a 120 ks observation of this quasar.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
