We propose a deep XMM 100 ksec observation of the A2744 a unique massive clustermerger: the Pandora cluster. A2744 is the first of the six Frontier FieldClusters to be observed with HST, reaching unprecedented depth. With theproposed observation we will: 1) study the thermodynamic properties andmetallicity of the complex merging taking place in the cluster core; 2) comparethe lensing and hydrostatic mass estimates of the cluster and the different subclumps identified; 3) map the large-scale matter distribution out to the virialradius where current data reveal possible substructure not yet confirmed thatmay contribute to the growth of the cluster. This data set will be of legacyvalue considering the HST Frontier Field initiative, we suggest to have no data proprietary right.

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.
