|Title||Observing a Narrow Line Seyfert 1 Galaxy in a peculiar state|
|Author||Dr Roland Walter|
|Description||We want to observe a Narrow Line Seyfert 1 galaxy with a very peculiar spectral energy distribution. Its prominent soft X-ray excess component is not detected in the ultraviolet, indicating a very narrow range of temperature when compared to normal AGNs. We want to probe the origin of the soft X-ray excess and to understand why this object is so peculiar. We believe that this special case will help understanding normal Seyferts.|

|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.
