In models for the nearly-grazing encounter between the spiral galaxies NGC2207/IC 2163, the two gas disks push shocks at several hundred km/s into eachother across a several kpc front. Evidence for this disk scraping is seen in theradio continuum image. XMM observations of NGC 2207/IC 2163 are requested (1) toconfirm the above scenario by detecting diffuse X-ray bremsstrahlung from theshock regions in the outer parts of the companion sides of these galaxies and(2) to determine the number, location, and nature of discrete X-ray sources. Theresults will show the early consequences of a grazing encounter.

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.
