| Abstract | We propose a 147 ks XMM-Newton observation of the galaxy cluster RXCJ0303.8-7752. Shallow observations show there is a tail-like structure with alength of 2-Mpc alongside the main cluster, which is the longest such featureever reported. The deeper observations proposed here are needed in order toreveal the merging and the formation history of this rare tail, and in a broadertext, to understand the heating and virialization processes of the ICM whenaccreting matter from subhalos. |

| 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. |
