Description | Detection and characterization of shock fronts in clusters is limited to a tiny number of objects. One of the major difficulties is that shocks occur in low surface brightness regions where available instrumentation has considerable difficulty in making measurements. Here we propose a novel observational and data analysis strategy allowing us to make reliable measures of the shock front in A754. The sensitivity afforded by our observation will also allow us to characterize parts of the outer regions of A754 in unprecedented detail. From a more general perspective ours may be viewed as a demonstration of the capability of the EPIC experiment to provide substantially improved measurements of cluster outer regions. Such measures are likely to remain unsurpassed for years to come. |

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. |
