Abstract The z=0.068 quasar MR2251-178 is a unique source because 1. it is a memberof a very small class of high luminosity AGN showing warm absorbers (WA)in their spectrum. 2 its WA is very different from WAs seen in low luminosityAGN, and 3. its high X-ray luminosity (L(2-10 kev)=1e45 erg/sec) and X-rayflux will allow a detailed investigation with XMM-RGS.We propose a 70 ks pointing that will allow us to measure 2-10 soft X-rayemission lines (depending on the properties of high ionization gas which isnot along our line-of-sight) and thus reveal the properties of the warmgas, its compositio and its relation to similar gas in Seyfert 1 galaxies.

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.
