| Description | A remarkable recent development is the discovery of cold fronts at very large radii in the Perseus cluster, that are much older than those in cluster cores. Because of this, diffusion processes have had much longer to broaden the edge, while instabilities have had longer to grow. Recently we extended the XMM mosaic of Perseus to reach the virial radius to the west, and have confirmed suggestions from ROSAT that the sloshing extends to the virial radius. Remarkably, our new XMM mosaic shows 2 edges near the virial radius. However we are only seeing a small section of them\: the full scale of the sloshing is yet to be revealed. We propose 4 observations to extend the Perseus mosaic to fully cover the sloshing near the virial radius, and fully reveal the extent of the mysterious double edge. |

| 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. |
