| Description | Recent discoveries in X-rays of massive and fast outflows in nearby AGNs have shown that AGN-driven winds may be a very effective way of providing the often invoked AGN feedback. To date, for obvious sensitivity limitations, detailed X-ray spectral studies have been however restricted to the nearest AGN and, at higher redshift, to a handful of QSOs which are mostly lensed. To start filling this gap, we propose here an exploratory X-ray spectral study on a small sample of 4 bona fide type-1, non-lensed and non-beamed QSOs selected among the X-ray brightest QSOs known to date at zvirgul2. Our main goal is to obtain X-ray spectra with a secure and high enough S/N to constrain the presence and properties of massive winds in high-z QSOs and serve as path-finder for future studies on AGN feedback. |

| 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. |
