We propose to observe the optically highly polarized Narrow-Line Seyfert 1.5galaxy IRAS 12397+3333 in order to study its complex warm absorber features withXMM-Newton.s RGS. This observation will enable us to determine the ionizationstates of the ionized gas around the central black hole and by the columndensities and blueshift of the absorption lines we can determine the gas outflowrate. In combination with other observational techniques such as opticalspectropolarimetry and by comparison with other XMM RGS observations of AGN withwarm absorbers we can test and fine-tune (unified) AGN models. RX J12397+3333 isone of a few known X-ray bright AGN with warm absorbers which have yet not beenobserved by XMM.

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.
