Description We propose XMM-Newton+HST observations of SPT-CLJ2228 5828, a high-redshift (z=0.73) galaxy cluster merger. It exhibits two widely-separated (940 kpc) centers in the galaxy distribution with counterparts identified in a weak lensing analysis. From an SPT-SZ map, the cluster gas appears to be located in between the two peaks of the galaxy distribution and mass map, suggesting a dissociative merger. If confirmed, SPT-CLJ2228 5828 would be among the widest dissociated mergers known. The requested high-resolution X-ray observations will allow us to confirm the dissociated merger nature and to constrain the cluster X-ray temperature and luminosity to 10%. We request complementary HST observations to substantially improve the mass reconstruction using strong and weak gravitational lensing.

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.
