Description Galaxy cluster mergers trigger Mpc-scaled shocks in the ICM, which can accelerate particles to relativistic energies to form arc-shaped radio relics. Last year, we discovered a spectacular radio relic in the Planck cluster A3411. The relic has a fragmentary morphology, at odds with the arc-shaped shocks predicted by hydrodynamical simulations. We propose for a 200 ks XMM observation to detect and characterize the shock at the radio relic. The combination of X-ray and radio data will provide the opportunity to (1) determine the shape of the shock surface; (2) model the merger event; and (3) test different shock acceleration models. Data on such puzzling objects is crucial to our understanding of relics.

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.
