Description A key concept in modern astrophysics is that galaxy interactions shape galaxy evolution. Though merging galaxies are in many ways understood, how galaxies behave in far more common, non-merging interactions, i.e. flybys, remains unknown. Based on our previous ROSAT work, suggesting that hot gas is expelled from merging spiral galaxies, we can now, by utilizing the high sensitivity and resolution of XMM-Newton, explore for the first time the details of the gas ejection and star-formation processes at various stages of a galaxy-galaxy flyby. Such a study will constrain our understanding of flyby encounters, the physics of star-formation and gas ejection, galaxy formation and evolution, the enrichment of the IGM, and the baryon content of the universe.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
