| Description | The XXL survey has constructed the most pure and reliable sample of distant (z>1) X-ray-selected clusters of galaxies, thanks to its well-calibrated selection function and our complete Chandra follow-up to identify any contaminating point sources. In this proposal we initiate a programme of deeper XMM observations of these clusters to measure their properties and evolution, examine their morphologies, compare them with distant SZE-selected clusters, and probe the parameter space where distant eROSITA clusters will be found. We request 268 ks to observe three clusters, completing an initial sample of six Chandra-validated z>1 XXL clusters. |

| 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. |
