Recent spectroscopic observations in the UV band have revealed high velocityoutflows in Narrow Absorption Line (NAL) quasars. We propose to initiate anexploratory survey to identify high velocity outflows of X-ray absorbingmaterial in NAL quasars. We will search for possible correlations between theamount of X-ray absorption and UV properties of the wind to better understandthe acceleration mechanism of quasar winds. We will place the absorbers of NALquasars in the context of other outflow phenomena and test models for theirnature. The detected X-ray brightest objects from the proposed survey will befollowed up with deeper observations to constrain better the kinematic andionization properties of the absorbers and ultimately constrain the mass outflow rates of NAL quasars.

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.
