We have recently identified an exceptional strong lensing cluster at z=1.335: Abright giant arc with a spectroscopically measured redshift z=3.29 is seen at alarge angular radius of 18 and two additional multiply lensed backgroundsources have been identified in recent HST imaging. XMM data are needed todetermine whether this remarkable lensing strength is generated by a singlemassive cluster with a deep potential well or projection effects of multiplecorrelated or uncorrelated structures along the line of sight. We request jointChandra observations to identify exclude point sources and VLT MUSE observationsto search for line-of-sight structures in the redshift distribution of galaxies.

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.
