      abstract     = {We investigate the hydrodynamic properties of a spherical
                      colloid model, which is composed of a shell of point
                      particles by hybrid mesoscale simulations, which combine
                      molecular dynamics simulations for the sphere with the
                      multiparticle collision dynamics approach for the fluid.
                      Results are presented for the center-of-mass and angular
                      velocity correlation functions. The simulation results are
                      compared with theoretical results for a rigid colloid
                      obtained as a solution of the Stokes equation with no-slip
                      boundary conditions. Similarly, analytical results of a
                      point-particle model are presented, which account for the
                      finite size of the simulated system. The simulation results
                      agree well with both approaches on appropriative time
                      scales; specifically, the long-time correlations are
                      quantitatively reproduced. Moreover, a procedure is proposed
                      to obtain the infinite-system-size diffusion coefficient
                      based on a combination of simulation results and analytical
                      predictions. In addition, we present the velocity field in
                      the vicinity of the colloid and demonstrate its close
                      agreement with the theoretical prediction. Our studies show
                      that a point-particle model of a sphere is very well suited
                      to describe the hydrodynamic properties of spherical
                      colloids, with a significantly reduced numerical effort.},
