CLUMP-3D.  Three dimensional lensing and multi-probe analysis of MACS J1206.2-0847, a remarkably regular cluster
Sereno, et al

Multi-wavelength techniques can probe the distribution and the physical properties of baryons and DM in galaxy clusters from they nner regions out to the peripheries.  Present a full 3d analysis combining strong and WL, X-ray surface brightness and temperature, and the SZ effect.  The method is applied to MACS J1206.2-0847, a remarkably regular, face-on, massive, M_200=1.1±0.2e15 Msun/h, cluster at z=0.44.  The measured concentration, c_200=6.3±1.2, and the triaxial shape are common to haloes formed in a LCDM scenario.  The gas has settled in a follows the shape of the gravitational potential, which is evidence of pressure equilibrium via the shape theorem.  There is no evidence for significant non-thermal pressure and the equilibrium is hydrostatic.
