Abstract Any understanding of the evolution of groups and their members, which ultimatelymeans the evolution of all galaxies, cannot be complete without detailed studiesat X-ray wavelengths, that probe the properties of the IGM and the interplaybetween galaxies, ISM and IGM. We propose here to observe an intriguingenvironment representative of a unique accretion scenario, possibly resultingfrom parallel evolution of two distinct subcondensations associated with NGC4756. We aim at 1) quantifying when and how sub-structures and early-typemembers evolve their own X-ray halo and 2) determining the role of the hot IGMin regulating galaxy activity (star formation and/or AGN).

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.
