Abstract	Using the largest Spitzer surveys (SWIRE & NDWFS) we uncovered an exceptionalpopulation of z~2 obscured and extremely luminous QSOs. We propose XMM-Newtonobservations of 11 sources from our unique sample of the 15 most luminousobscured QSOs currently known. These data will enable us to place constraints onthe space density of obscured and extremely luminous QSOs, their contribution tothe X-ray background, the high-z and high-L absorption distribution, and theobscured AGN fraction. The properties of the absorber will be also investigatedby analyzing the dependency of the dust covering factor with the AGN luminosity,and comparing dust extinction with X-ray absorption. In addition, theseobservations will provide new templates for obscured QSOs.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
