Description We propose a 80ks XMM-Newton observation for the galaxy cluster, RXCJ2359-6042 (A4067). This is a unique system, where a compact bullet penetrates an extended, low density cluster at a low redshift (z=0.0992). We can clearly watch the process how the bullet component is stripped of its layers outside the core. We can also tentatively identify a Mach cone with a wide opening angle, a contact discontinuity inside, and infer a mild shock. A deeper XMM-Newton observation is absolutely crucial to characterise the merging processes with imaging spectroscopy in more detail in this unique system.

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.
