Description We propose a 90ks XMM--Newton observation of the Narrow Line Seyfert 1 galaxy RE 1034+396. This has the strongest soft X-ray excess ever seen in an active galaxy (AGN). It also has extremely low absorption in the line-of-sight, so has excellent FUSE-EUVE-HST data to delineate the lower energy extent of the soft X-ray excess and especially how this connects onto the accretion disc emission. RE1034+396 thus represents the extreme of the NLS1 population, and the best hope for constraining the nature of the soft excess.

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.
