| Description | We propose to observe the merging cluster A 3128 in the Horologium-Reticulum supercluster for 100 ks. A 3128 has two X-ray cores. Observations indicate that one core is moving at Mach number Mvirgul6 through the cluster. This high velocity causes shocks, which heat the plasma and give rise to particle acceleration, which in turn can produce non-thermal emission. The high Mach number makes A 3128 one of the best targets to investigate shocks created by supersonic infall velocities in clusters of galaxies and to look for non-thermal emission. The superior effective area, spectral resolution and sensitivity make XMM-Newton an ideal instrument to look for the non-thermal emission and study the merger by mapping the temperature, density and metallicity distribution in the cluster. |

| 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. |
