| Description | Suzaku observations of the outskirts of the Virgo cluster have revealed a very high gas mass fraction to the North and South, while the entropy unphysically decreases outwards. This suggests a very high level of clumping and/or non thermal pressure support. XMM.s high spatial resolution allows it to constrain the level of gas clumping, by binning images into a tessellation. Here we propose 5 XMM observations, totaling 155ks, to cover the regions of Virgo where the Suzaku has found the highest gas mass fraction and lowest entropy. This will allow us to constrain gas clumping, to clumping correct the thermodynamic profiles, and infer the level of non thermal pressure support. Virgo.s proximity allows us to probe clumping with 100x better spatial resolution than before. |

| 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. |
