Description Recent spectroscopic observations in the UV band have revealed high velocity
outflows in Narrow Absorption Line (NAL) quasars. Our analysis of exploratory
XMM-Newton observations of NAL quasars indicates that their UV and X-ray
properties connect smoothly to those of BAL quasars. The proposed expansion of
our exploratory sample will allow us to place constraints on correlations
between the amount of X-ray absorption and UV properties of the wind to better
understand the acceleration mechanism of quasar winds. We will test existing
models of the nature of NAL quasars. The detected X-ray brightest objects from
the proposed survey will be followed up with deeper observations to constrain
the kinematic and ionization properties of the absorbers and ultimately constrain their mass outflow rates.

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.
