| Description | Deep good-seeing HAWK-I Ks images complemented with g+z photometry provide a cost-effective and similarly sensitive alternative to HST for deep weak lensing measurements of massive high-redshift clusters. We propose such observations for the nine z>0.7 clusters with the strongest SZ signal in the new 2,770 deg^2 SPTpol Extended Cluster Survey, aiming to map their dark matter content and obtain accurate estimates of their true mass scale. |

| 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. |
