The narrow-line Seyfert 1 galaxy IRASvirgul17020+4544 shows evidence for a warmabsorber in low-resolution X-ray spectra, and its high polarization suggeststhat it is dusty. We propose an observation of IRASvirgul17020+4544 in order todiagnose the nature of dusty warm absorbers, and also to investigate thepossible link between the presence of high polarization and the lower-ionizationwarm absorber. This source is also of interest in the iron K-line, which wassuggested to be broad, strong and ionized. We also aim to investigate the ironK-features with the EPIC.

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.
