| Description | The idea that ellipticals can be formed from the merger of two spirals is a key concept in modern astrophysics. An outstanding issue however, is that of how the gas is removed from the system. Our previous work with ROSAT hinted that the mechanism was massive gas ejection at the nuclear merger stage. Details of the expelled gas properties, at various stages of the merger process, can now be explored for the first time by utilizing the high sensitivity and resolution of XMM. Such a study will constrain our understanding of the merger process, the physics of star formation and gas ejection, elliptical galaxy formation, 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. |
