  In a large region of the supersymmetry parameter space, the annihilation
cross section for neutralino dark matter is strongly dependent on the relative
velocity of the incoming particles. We explore the consequences of this
velocity dependence in the context of indirect detection of dark matter from
the galactic center. We find that the increase in the annihilation cross
section at high velocities leads to a flattening of the halo density profile
near the galactic center and an enhancement of the annihilation signal.
