In this talk I report upon our results on the intracluster medium (ICM) of two clusters at the time when first clusters start to emerge from the cosmic web, z~2. Results are derived from new, high resolution, deep SZ and X-ray data providing us with the measurement of the two most distant resolved pressure profiles. IDCSJ1426 cluster at z=1.75 has a core whose properties are not far from the final stage, while the remaining part of the cluster is experiencing a sizable gas, heat and entropy transfer. JKCS041 at z=1.80 is caught just after a major merger event as evidenced by its SZ-X-ray peak offset, its low central pressure, and its low Compton-Y parameter compared to its WL mass. Comparison with plausible descendents shows that its ICM will experience major changes at all radii.

Brief CV of Dr. Strefano Andreon:

He is an astronomer (69 first-authored refereed papers, about 2000 citations to them, h-index 39; from ADS) and statistician (follow my signature below). His main interest is understanding how clusters of galaxies and galaxies in clusters evolve from an observational point of view and using Bayesian methods that he teaches (so far at 13 universities spread in 7 countries).  His top three most cited papers address the mass dependency and scatter of the stellar and gas fractions, the scaling between richness and mass, and the evolution of faint galaxies on the red-sequence. He discovered the galaxy cluster at the second highest redshift known, JKCS041 at z=1.803 (the most distant for over a decade). He was one of the first astronomers using artificial intelligence tools (neural networks, self organizing maps) for photometric redshift and object detection at the end of the 90's and, starting from 2005, bayesian methods for many astrophysical applications.
