|Description||Understanding the feedback mechanism in AGN at their (z~2) peak of cosmic activity is key to understand the co-evolution of SMBHs and galaxies. Recent discoveries in X-rays of massive outflows in nearby AGNs have shown that AGN-driven winds may be an effective way of providing this feedback. To date, detailed X-ray spectral studies have been however restricted to the nearest AGN and, at higher z, to a handful of QSOs which are mostly lensed. We thus propose here an exploratory study on a small sample of bona fide type-1, non-lensed and non-beamed QSOs selected among the X-ray brightest QSOs at z~2 already detected in X-rays. Our main goal is to obtain X-ray spectra with a secure and high enough S-N to constrain the presence of massive winds in high-z QSOs, and serve as pathfinder for future 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.
