| Description | We propose to observe 4 clusters of galaxies with gas temperatures between 3-5 keV. This is a critical temperature range in the evolution of clusters and spans the interval from open systems (i.e., groups and poor clusters that probably experienced significant gas loss) to closed systems (i.e., rich clusters that retained the gas shed by galaxies). Our proposed XMM observations will determine the temperature and entropy profile of the gas, along with the distribution of heavy elements. Our sample is chosen so that the radius r_500 (within which the mean density is 500 times the critical density) falls within the EPIC detectors. From these observations, we can determine the gravitating mass, gas mass fraction, and Fe mass-to-light ratio at comparable physical radii |

| 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. |
