| Abstract | The contribution of AGNs to the Far Infrared Background is still uncertain, andis strictly related to the understanding of the energy source of ULIRGs.If a significant fraction of ULIRGs is powered by AGNs, these AGNs haveto be both luminous (L(2-10 keV)~ 10^45 erg s^-1) and heavily absorbed in theX-rays. We propose to use the XMM observational capabilities in the hard X-rayto look for these QSO2s in a well defined sample of ULIRGs.We will be able to estimate a stringent lower limit of the AGN contribution toULIRGs and we expect to increase the number of known QSO2s. Comparing the X-rayand the FIR emission of these objects, we will be able to study the correlationbetween the FIR and hard X-ray backgrounds in the near Universe. |

| 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. |
