Description Recently, we have discovered an amzing 3 Mpc radio relic. Its coherent linear morphology and enormous size are very difficult to understand in the standard scenario that relics trace shocks in the ICM induced by massive cluster mergers. With our proposed observations we will determine (i) the presence of shock waves and their properties, (ii) the number of merging sub-clusters and dynamical state of the cluster, and (iii) the temperature structure of the ICM. This will allow us then to address the following questions: (1) are we witnessing a very special configuration consisting of multiple merging events that collectively conspire to yield a linear structure? (2) is there a compelling need for a more sophisticated particle acceleration mechanism?

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.
