| Abstract | The Planck Cosmological Reference Sample of 189 SZ-selected provides theopportunity to define the low redshift benchmark for cluster evolution studies.To completely characterize the sample requires 12 XMM-Newton observations, eachsufficient to measure the key mass proxy M_{YX} to an accuracy of 5% or better.In addition, the observations will enable detailed studies of cluster scalingrelations, measurement of the scatter around these relations, and enableimprovements in the Planck SZ measurements using accurate X-ray determinedpositions and sizes. The ultimate goal is to compare high z and low z clustersamples to constrain cosmological parameters as well as to understand anydifferences between X-ray and SZ cluster selection functions. |

| 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. |
