Description We have discovered an extraordinarily long, narrow steep spectrum radio relic in the galaxy cluster CIZA J2242.8+5301. The relic has a remarkable radio spectral index gradient perpendicular to its long axis and polarization points to a magnetic field parallel to it. Here we propose deep X-ray observations to (i) confirm the presence of a shock front at the position of the radio relic, (ii) determine the shock physical conditions, (iii) characterize the dynamical state of the cluster, and (iv) map the temperature distribution. These observations will (i) provide conclusive evidence for the existence of diffusive shock acceleration and, (ii) constrain scenarios connecting the properties of shock fronts, particle acceleration mechanisms, and the occurrence of radio 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.
