Description | We propose a 10 ks snapshot of the Eastern edge of the Perseus Cluster, along a large-scale structure filament seen in the galaxy distribution. This is the only region so far where we have detected emission from beyond the virial radius of this cluster with Suzaku, but the systematic uncertainty due to the underlying point source flux is much larger than the statistical error of the measurement. This observation will allow us to detect point sources an order of magnitude fainter than with Suzaku and thus decrease this systematic uncertainty by a factor of 3-4. XMM-Newton will therefore play an important role in confirming this detection beyond the virial radius, and give us important insight into the physics at the edge between galaxy clusters and large-scale structure filaments. |

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. |
