| Description | Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. Optical studies hinted, and our previous XMM-Newton observations confirmed, that some superluminous disk galaxies are BCGs. The existence of such a BCG population is at odds with our understanding of the formation of these galaxies. Our AO-18 XMM-Newton program aimed to confirm the presence of additional superluminous disk galaxies at the center of galaxy clusters. However, due to soft proton flares, one of the most promising superluminous spiral galaxy and its host cluster could not be characterized. We request a short follow-up observation to carry out a dependable analysis of the galaxy cluster and its superluminous spiral BCG. |

| 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. |
