| Abstract | We propose to observe the merging cluster A 3128 in the Horologium-Reticulumsupercluster for 100 ks. A 3128 has two X-ray cores. Observations indicate thatone core is moving at Mach number M~6 through the cluster. This high velocitycauses shocks, which heat the plasma and give rise to particle acceleration,which in turn can produce non-thermal emission. The high Mach number makes A3128 one of the best targets to investigate shocks created by supersonic infallvelocities in clusters of galaxies and to look for non-thermal emission. Thesuperior effective area, spectral resolution and sensitivity make XMM-Newton anideal instrument to look for the non-thermal emission and study the merger bymapping the temperature, density and metallicity distribution in the cluster. |

| 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. |
