Abstract GT - Detailed X-ray spectral information will help to distinguish between theemission mechanisms present in this bright LINER. If it contains a dwarf AGN,it should show a compact, variable source whose X-ray emission has a non-thermalpower-law form. It may also show strong Fe K-alpha line emission produced byfluorescence in cold matter. On the other hand, nuclear starbursts arefrequently extended over kpc scales and are expected to show thermal spectracharacterised by coronal X-ray emission lines.

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.
