Description Narrow Line Seyfert 1 galaxies have strong spectral features in the 0.1-10keV band and strong variability, making them very interesting XMM targets. These properties are probably due to the emission orginating in the inner regions of ionized disks around massive black holes. We propose to observe two typical NLS1, PG 1244 and PG 1404, in order to test this hypothesis using spectral models of ionized disks developed by us. If correct, the oxygen features offer a further means to determine the relativistic X-ray line broadening.

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.
