Abstract We wish to re-observe 8 high SNR Planck all-sky survey-discovered clusters at0.1<z<0.5. Existing XMM 10 ks snapshot observations of variable quality, carriedout as part of Planck catalogue validation, suggest that they are all hot (kT >5 keV), high mass objects with complex morphologies and density profiles farshallower than those of X-ray-selected cluster samples in the same mass range.We will measure density, temperature, entropy and pressure profiles and comparewith reference local and distant data from X-ray-selected samples. Deep X-rayobservations of these extreme objects will allow us to precisely quantify howthese new SZ-selected clusters differ from X-ray selected clusters, and assesstheir impact on mass scaling relations and X-ray and SZ 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.
