Abstract We propose to make XMM observations of several BAL quasars that we expect willyield high signal-to-noise detections. The proposed systems exhibit veryinteresting, and in some cases extreme properties, that cover a wide range ofthe BAL parameter space. The proposed targets have either been previouslydetected in X-rays or are extremely bright and known to be polarized in theoptical band. With these observations we will constrain the BAL columndensities, search for correlations of BAL column densities with X-rayluminosity, optical polarization, and gas outflow velocities. Finally we willmake use of the unique capability of XMM to simultaneously observe variable BALsystems in both the X-ray and UV bands and apply these findings to test the

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.
