| Description | GT- Metals injected into the hot gas in galaxy groups preserve a record of the history of chemical evolution and gas ejection for their constituent galaxies. The ratio of Fe to alpha elements as a function of radius will constrain the history of SNI and SNII activity, and emission from individual group galaxies will constrain the stripping of gas and dark halos. We have selected a sample consisting of the two most X-ray luminous Hickson compact groups, and a loose group of comparable X-ray brightness. Comparison between these systems will clarify the nature of compact groups and the dynamical evolution of all groups. |

| 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. |
