We propose XMM observations of two LINER-type ultraluminous infrared galaxiesfor which our infrared 3--4 micron slit spectroscopy has revealed the presenceof centrally-concentrated energy sources, as is expected for a buried AGN. Themain goal is to obtain direct X-ray evidence that the centrally-concentratedenergy sources are indeed buried AGNs (strong 2--10 keV X-ray emitter), and notunusually centrally-concentrated starbursts (weak X-ray emitter).

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.
