| Description | Groups of galaxies are in many respects galaxy clusters scaled to smaller sizes, but the essential differences that are found give important clues to the state and evolution of the intracluster medium in clusters and groups. Groups may have experienced some major gas loss and seem to have a stronger enrichment by alpha-elements in comparison to clusters. To better understand and evaluate these effects we need to get better data on the temperature structure and metallicity gradients of groups. For the study we have selected one of the most X-ray luminous groups dominated by an elliptical galaxy. |

| 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. |
