Description It is widely accepted that the broad absorption line (BAL) outflow exists in most quasars with a small covering factor. Various evidences show that equatorial outflows are responsible for the BALs in most BALQSOs. By searching for radio variable quasars in SDSS, we built a sample of BALQSOs with polar outflows. It is very likely that polar outflows are associated with relativistic jets, and their origins should be different from the equatorial outflows in the majority of BALQSOs. We propose an XMM snapshot survey to a)check whether strong X-ray absorption, one of the most prominent characteristics of BALQSOs, exist in the polar outflows b)whether face-on BALQSOs are otherwise X-ray normal c)provide a baseline for future extensive X-ray studies.

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.
