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

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.
