| Abstract | We propose to observe 15 low-mass SZ selected galaxy clusters from arepresentative sample of 45 objects at 0.5<z<0.9, comprising the majority of thelow-mass part of a GT Programme of high resolution (20) SZ observations withNIKA2. With M500>3x10e14 Msun, the full sample, extracted from Planck and ACT,covers an unprecedented mass range. Archival X-ray data are available at highmass. Combining the gas density from XMM and the pressure from NIKA2, we willdouble the (log) mass range of our study of the pressure, entropy and HE massprofiles, their dispersion, and the relations between Ysz, Yx and M500. Thesample adds 3 Gyr of look-back time beyond z>0.5, and will serve as an importantprobe of the impact of gravitational and non-gravitational processes on the ICM. |

| 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. |
