| Description | Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. Recent studies hinted that superluminous disk galaxies could be the BCGs of a subset of galaxy clusters. The existence of such a BCG population is at odds with our understanding about the formation of these galaxies. However, based on optical observations, it is not possible to constrain whether the superluminous disk galaxies reside at the center of galaxy clusters. In this proposal, we request 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 whether superluminous disk galaxies 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. |
