| Abstract | We propose a 122 ks XMM-Newton observation of the merging galaxy cluster MACSJ1752+4440. The system is characterized by remarkable double bullets in X-rayand the symmetric giant double radio relics, which together indicate ahigh-speed post-merger resembling the Bullet Cluster, however, observed at alater phase. This unique combination offers a rare opportunity to addresslong-standing puzzles in cluster mergers including generation/propagation ofplasma shocks and particle acceleration. The observation will enable us to 1)measure X-ray shocks at the location of the relics, 2) reveal thermodynamicproperties of the double bullets, 3) constrain the merger scenario, and 4)quantify the re-acceleration efficiency of diffusive shock acceleration. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
