Title XMM Study of Ultrasoft Narrow-Line Seyfert 1 Galaxies SSC_4

Author Dr Michael Watson
Description GT- We propose to extend X-ray studies of ultrasoft narrow-line Seyfert 1 galaxies (NLS1) by making XMM observations of the most interesting members of this class. The broad band, large effective area and high spectral resolution of XMM will allow the best X-ray studies of NLS1 to date. We will measure their soft and hard X-ray continua, their spectral features and their strong flux and spectral variability.

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.
