Description Brightest Cluster Galaxies (BCGs) residing in the hearts of galaxy clusters are massive ellipticals with little star formation. A recent study hinted that massive, blue, star-forming galaxies ("super spirals") may be the BCGs of several galaxy clusters. Clearly, such a BCG population would be at odds with our understanding about the formation of these galaxies. However, based on the presently available data it could not be unequivocally demonstrated that super spirals are truly BCGs. Therefore, we request exploratory XMM-Newton observations to map the morphology of the intracluster medium, measure the offsets between the peak of the diffuse X-ray emission and the position of the candidate BCGs, and hence directly probe if super spirals are true BCGs.

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.
