Description | Galaxy clusters are the end point of structure formation, with their outskirts being the regions where smaller structures are still accreting onto the main halo. The distribution of the gas in these regions is expected to be clumpy and asymmetric, with an important contribution from non-thermal pressure support. Following the success of our large XMM-Newton program we propose to map the outer regions of 3 merging galaxy clusters. We will perform an azimuthal analysis in sectors, exploring in detail the violation from hydrostatic equilibrium along several directions out to R200. With a required time of just 200 ks our program will provide the first assessment of the integrated non-thermal pressure content in a complete sample of galaxy clusters. |

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. |
