Abstract It has been revealed that groups of galaxies contain a large amount of hot gasas well as galaxy clusters. Therefore, observations of X-ray emission fromgroups of galaxies allow us to estimate mass distribution and elementalabundances. However, only elliptical-dominant groups have been investigateduntil now, due to X-ray faintness of spiral-dominant ones. Here we propose toobserve a spiral-dominant group of galaxies HCG 57 in order to investigatedifferences of temperature, metal, mass, and entropy between spiral-dominant andelliptical-dominant.

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