Description Relics are diffuse radio sources thought to trace shocks at the periphery of merging clusters. LOFAR, with its unique resolution and sensitivity, is revolutionizing the field by opening a new window of discovery. The LOFAR survey recently discovered a rare example of double relics in a low-mass cluster, confirmed as a 3:1 merger by our Cy21 Chandra observations. The bright relics are located exceptionally far away from the cluster core -- at about R500 (1.3 Mpc). The properties of the radio sources are hard to reconcile with current relic formation models, given the low cluster mass. We propose XMM-Newton observations to study the luminosity and temperature substructure, understand the cluster merger history and place tight constraints on relic formation models.

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.
