| Abstract | Continuing controversy surrounds the interpretation of relativistic iron K linesin AGN. Broad emission is often present, but doubts remain as to whether complexabsorption can account for the spectral curvature. Mrk 335 represents a key testcase, in that it shows a broad, redshifted iron line but no evidence for ionizedabsorption. The sole remaining doubt is whether the broad line can be accountedfor by neutral partial covering. We propose an orbit-length observation todetermine this. Our second major goal is to confirm a redshifted absorption lineindicative of relativistic inflow at 0.14c. This observation will help eliminateany remaining doubt over whether future generations of X-ray missions canexploit the potential of the iron lines as a probe of accretion physics and strong gravity. |

| 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. |
