Recent spectroscopic observations in the UV band have revealed high velocityoutflows in Narrow Absorption Line (NAL) quasars. Our analysis of exploratoryXMM-Newton observations of NAL quasars indicates that their UV and X-rayproperties connect smoothly to those of BAL quasars. The proposed expansion ofour exploratory sample will allow us to place constraints on correlationsbetween the amount of X-ray absorption and UV properties of the wind to betterunderstand the acceleration mechanism of quasar winds. We will test existingmodels of the nature of NAL quasars. The detected X-ray brightest objects fromthe proposed survey will be followed up with deeper observations to constrainthe kinematic and ionization properties of the absorbers and ultimately constrain their mass outflow rates.

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.
