|Title||Relativistic emission and absorption in the Seyfert 1 galaxy Mrk 335|
|Author||Dr Kirpal Nandra|
|Description||Continuing controversy surrounds the interpretation of relativistic iron K lines in AGN. Broad emission is often present, but doubts remain as to whether complex absorption can account for the spectral curvature. Mrk 335 represents a key test case, in that it shows a broad, redshifted iron line but no evidence for ionized absorption. The sole remaining doubt is whether the broad line can be accounted for by neutral partial covering. We propose an orbit-length observation to determine this. Our second major goal is to confirm a redshifted absorption line indicative of relativistic inflow at 0.14c. This observation will help eliminate any remaining doubt over whether future generations of X-ray missions can exploit the potential of the iron lines as a probe of accretion physics and strong gravity.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
