cds-question@unistra.frgalaxy-clustersx-ray-sourcesgalaxy-classification-systemsWe present a detailed study of the integrated total hydrostatic mass profiles of the five most massive (M_500_^SZ^>5x10^14^M_{sun}_) galaxy 500 clusters selected at z~1 via the Sunyaev-Zel'dovich effect. These objects represent an ideal laboratory to test structure formation models where the primary driver is gravity. Optimally exploiting spatially-resolved spectroscopic information from XMM-Newton and Chandra observations, we used both parametric (forward, backward) and non-parametric methods to recover the mass profiles, finding that the results are extremely robust when density and temperature measurements are both available. Our X-ray masses at R_500_ are higher than the weak lensing masses obtained from the Hubble Space Telescope (HST), with a mean ratio of 1.39^+0.47^_-0.35_. This offset goes in the opposite direction to that expected in a scenario where the hydrostatic method yields a biased, underestimated, mass. We investigated halo shape parameters such as sparsity and concentration, and compared to local X-ray selected clusters, finding hints for evolution in the central regions (or for selection effects). The total baryonic content is in agreement with the cosmic value at R_500_. Comparison with numerical simulations shows that the mass distribution and concentration are in line with expectations. These results illustrate the power of X-ray observations to probe the statistical properties of the gas and total mass profiles in this high-mass, high-redshift regime.2018A&A...617A..64Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/617/A64CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/617/A64https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/617/A64http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/617/A64https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/617/A64https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/617/A64http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/617/A64GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/617/A64/clusters (List of clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/617/A64/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/617/A64/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/617/A64/clusters?GETtext/xml+votable180.050000true326.6458333-46.54833330.0055555555555555566/33878 39043 45873 46345 46642https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/617/A64?format=asciiX-rayOpticaldefaultJ/A+A/617/A64/clustersList of clustersrecnoRecord number assigned by the VizieR team.
