|Title||Definitive Observations of an Accretion Disk Wind in the Quasar MR 2251-178|
|Author||Dr James Reeves|
|Description||The bright, nearby QSO MR 2251-178 was the first AGN where a warm absorber was detected. Subsequent observations have shown that there are at least two warm absorber components; a low ionisation soft X-ray absorber and a putative high velocity (0.07c) wind. We propose a deep (336 ks total) observation of MR 2251-178 in order to determine the origin of the outflow. Our goals are; (i) to establish the nature of the high ionisation absorber, e.g. as part of a disk wind, through high S-N observations in the iron K band and (ii) obtain a high resolution RGS spectrum of the soft X-ray absorber. Together with our recently approved large Chandra-HST project, this will allow us to deduce the kinematics, location and energetics of the outflow to unprecedented accuracy.|

|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.
