We propose to observe a small group of Hyperluminous Infrared Galaxies(L_IR>10^13 L_SUN) at redshift between 0.6 and 1.2, which according to ouranalysis based on Spitzer 5-8 micron spectra hide obscured active nuclei in thequasar luminosity range. These AGNs are therefore among the few known QSO2s inthe redshift range where the bulk of the X-ray background is produced. TheXMM-Newton observations will unveil the X-ray properties of these extremeobjects, confirming their QSO2 nature, measuring their column density, andestimating their X-ray to bolometric emission, and thus their r^ance for theX-ray background.

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.
