Abstract | GT- We propose to extend X-ray studies of ultrasoft narrow-line Seyfert 1galaxies (NLS1) by making XMM observations of the most interestingmembers of this class. The broad band, large effective area and highspectral resolution of XMM will allow the best X-ray studies of NLS1 todate. We will measure their soft and hard X-ray continua, their spectralfeatures and their strong flux and spectral variability. |

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. |
