| Description | Any understanding of the evolution of groups and their members, which ultimately means the evolution of all galaxies, cannot be complete without detailed studies at X-ray wavelengths, that probe the properties of the IGM and the interplay between galaxies, ISM and IGM. We propose here to observe an intriguing environment representative of a unique accretion scenario, possibly resulting from parallel evolution of two distinct subcondensations associated with NGC 4756. We aim at 1) quantifying when and how sub-structures and early-type members evolve their own X-ray halo and 2) determining the role of the hot IGM in regulating galaxy activity (star formation and/or AGN). |

| 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. |
