We propose to observe 15 galaxy clusters from the low-mass part of arepresentative SZ-selected sample of 45 objects at 0.5<z<0.9, forming a GTProgramme of high-resolution (<18) SZ observations with NIKA2. The full sample,extracted from Planck and ACT, covers an unprecedented mass range at theseredshifts. Archival X-ray data are available at high mass. Combining the gasdensity from XMM and the pressure from NIKA2, we will study high precisionindividual pressure, entropy and HE mass profiles, their dispersion, and therelations between Ysz, Yx and M500. The present sample doubles the (log) massrange, allowing us to better probe the impact of non-gravitational processes onthe 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.
