Description | We propose to observe the northwest radio relic region of the cluster Abell 2256 for 60 ksec, after a previous XMM-Newton observation, in order to localize the nonthermal hard X-ray emission detected by BeppoSAX. The energy range and the spectral capabilities of EPIC are able to disentangle the nonthermal radiation from the thermal emission in the radio relic, likely associated with the ongoing merger of a subcluster with the main cluster. Besides, we can firmly verify the suggested link between particle acceleration processes due to merger events and the formation of extended radio regions and nonthermal X-ray emission. |

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. |
