1. At large radii, radial velocity dispersion exhibit strange behavior. 2. The velocity dispersion of stars at the center of the cluster is. 3. Here, the velocity dispersion is much smaller. 4. Where ? V 2 is the velocity dispersion and G is the gravitational constant. 5. Typical velocity dispersion of galaxies within the Local Sheet is only in the radial direction. 6. When a wave propagates through subsurface materials both energy dissipation and velocity dispersion takes place. 7. Modal dispersion during propagation in the waveguide then provides group velocity dispersion to the signal. 8. Near the core, the stars have a velocity dispersion of 136 ?20 km / s. 9. The result of group velocity dispersion , whether negative or positive, is ultimately temporal spreading of the pulse. 10. The bulge component is similar to elliptical galaxies in that it is pressure supported by a central velocity dispersion .
