Description The Dark Energy Survey (DES) is currently the pre-eminent optical-near-IR survey for cosmology. DES uses four probes to study the physical nature of dark energy, including clusters of galaxies. To unlock the full potential of DES clusters, we require precise information of the galaxy-richness to halo-mass scaling relation, i.e. its slope, normalisation, and scatter. Of these, the least well known is the scatter. Therefore, one of the highest priorities for DES is to improve measurements of the scatter (and its evolution). For this, X-ray observations of a statistically complete sample are essential (archival, including serendipitous, observations are insufficient). We propose XMM observations (totaling 283ks) of 14 DES clusters, to complete a sample of 40 of the richest clusters in DES

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.
