|Description||Feedback from accreting SMBHs is now a standard ingredient in galaxy formation models but direct observations have been scarce. Using SDSS and the VLT, we identified a population of quasars at z=2.5 exhibiting signatures of extremely fast, dusty winds on galaxy-wide scales. Our proposed observations of these quasars will allow us to determine:(1) the X-ray luminosity to see if it is sufficient for driving powerful galaxy-wide winds.(2) The spectral slope to determine if the SED is conducive to wind launching. (3) The column density of the winds neutral gas component. These objects may prove to be the key to understanding quasar feedback at the epoch of peak galaxy formation, and X-ray observations are necessary to determine their energetics and physical roperties.|

|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.
