Description High velocity outflows are ubiquitous in quasars and an important part of SMBH evolution. They might even be necessary to carry away angular momentum and facilitate disk accretion. Studies of broad absorption line (BAL) quasars have revealed large X-ray absorbing columns and some tentative UV-X-ray correlations consistent with radiative acceleration in accretion disk winds. But BALs are only part of the story - sampling a narrow range of flow types or viewing angles. We propose XMM observations of quasars with high-velocity mini-BALs and weak-borderline BALs to extend the range of measured outflow parameters, test the BAL correlations-physical models, and solidify constraints on the global wind geometry, orientation, acceleration, mass loss rates, launch radii, etc.

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.
