On the entrainment of dark matter to the center of the Galaxy.

Estimates are given of the amount of dark matter that is entrained to the center of the Galaxy due to the formation and presence of the central component. Both an isothermal and an adiabatic model of the dark matter distribution are considered. In the isothermal model, the typical dark matter density enhancement is large enough to make the Cos-B satellite observations sensitive to γ-rays from dark matter annihilations near the galactic center if the dark matter is composed of weakly interacting stable particles such as the supersymmetric dark matter candidates, wheras in the adiabatic model it is about a factor of five too small.
