The galaxy phase-space distribution in galaxy clusters provides insights into the formation and evolution of cluster galaxies , and it can also be used to measure cluster mass profiles . We present a dynamical study based on \sim 3000 passive , non-emission line cluster galaxies drawn from 110 galaxy clusters . The galaxy clusters were selected using the Sunyaev-Zel ’ dovich effect ( SZE ) in the 2500 deg ^ { 2 } SPT-SZ survey and cover the redshift range 0.2 < z < 1.3 . We model the clusters using the Jeans equation , while adopting NFW mass profiles and a broad range of velocity dispersion anisotropy profiles . The data prefer velocity dispersion anisotropy profiles that are approximately isotropic near the center and increasingly radial toward the cluster virial radius , and this is true for all redshifts and masses we study . The pseudo-phase-space density profile of the passive galaxies is consistent with expectations for dark matter particles and subhalos from cosmological N -body simulations . The dynamical mass constraints are in good agreement with external mass estimates of the SPT cluster sample from either weak lensing , velocity dispersions , or X-ray Y _ { X } measurements . However , the dynamical masses are lower ( at the 2.2 \sigma level ) when compared to the mass calibration favored when fitting the SPT cluster data to a \Lambda CDM model with external cosmological priors , including CMB anisotropy data from Planck . The discrepancy grows with redshift , where in the highest redshift bin the ratio of dynamical to SPT+Planck masses is \eta = 0.63 ^ { +0.13 } _ { -0.08 } \pm 0.06 ( statistical and systematic ) , corresponding to a 2.6 \sigma discrepancy .
