| Abstract | GT-Redshift surveys of extragalactic IRAS sources have revealed a class of Ultraluminous IRAS Galaxies (ULIRGs). The proposed XMM observations of ULIRGswill allow us to (i) precicely determine the intrinsic X-ray column density ofneutral hydrogen and warm absorbers and to compare this with the IR-opticalreddening, (ii) compare the relative amounts of the soft and hard flux to further deconvole the relative contributions from the starburst- and block holeaccretion processes in ULIRGs, (iii) search for iron line emission. |

| 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. |
