The unusual properties of Narrow-line Seyfert 1 galaxies are thoughtto result from a higher accretion rate relative to Eddington thanbroad-line Seyferts. Luminous NLS1s should have the highest accretionrates of all. X-ray observations are crucial to the study of highaccretion rate objects, as the effects of the high accretion rate areexpected be revealed by the radiation emerging in the vicinity of theblack hole. We propose observations of a small sample ofquasar-luminosity NLS1s in order to characterize their X-ray and broadband properties and constrain high accretion rate models.

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.
