title = "LoCuSS: Testing hydrostatic equilibrium in galaxy clusters",
abstract = "We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 control systematic biases to sub-4 per cent, and our hydrostatic measurements of the same achieve excellent agreement betweenXMM-Newton and Chandra. The mean ratio of X-ray to lensing mass for these 50 clusters is βX = 0.95 ± 0.05, and for the 44 clusters also detected by Planck, the mean ratio of Planck mass estimate to LoCuSS lensing mass is βP = 0.95 ± 0.04. Based on a careful like-for-like analysis, we find that LoCuSS, the Canadian Cluster Comparison Project, and Weighing the Giants agree on βP = 0.9-0.95 at 0.15 < z < 0.3. This small level of hydrostatic bias disagrees at ~5σ with the level required to reconcile Planck cosmology results from the cosmic microwave background and galaxy cluster counts.",
