Description The Shapley supercluster is by far the largest mass cencentration in the nearby universe (z<0.1). For a good mass estimate it is necessary to know the dynamical state of the supercluster. We propose to study the centre and at the same time the richest cluster in the supercluster, A3558. Previous X-ray observations showed hints for merging in this cluster. From a combined morphological and spectral analysis we want to determine the dynamical state of the cluster and estimate its mass.

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.
