Abstract | The Shapley supercluster is by far the largest mass cencentration in the nearbyuniverse (z<0.1). For a good mass estimate it is necessary to know the dynamicalstate of the supercluster. We propose to study the centre and at the same timethe richest cluster in the supercluster, A3558. Previous X-ray observationsshowed hints for merging in this cluster. From a combined morphological andspectral analysis we want to determine the dynamical state of the cluster andestimate its mass. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
