| Description | We propose to obtain spatially resolved X-ray spectroscopy of a sample of 20 massive (M>5e+14M_sun) clusters detected blindly by Planck in the redshift range 0.7<z<0.9. Using for the first time a statistically significant sample in this regime, we will extend our study of the pressure, entropy and mass profiles, their dispersion, and the fundamental scalings between etween YSZ, YX and M500, of this extreme-mass population back to a time when the Universe was 46 per cent of its present age. The sample constitutes an important probe of the physics of gravitational collapse on cluster scales, and will be of large legacy value for the cosmological exploitation of the Planck sample. |

| 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. |
