  Bose-Einstein condensate dark matter model and Randall-Sundrum type 2
brane-world theory are tested with galactic rotation curves. Analytical
expressions are derived for the rotational velocities of test particles around
the galactic center in both cases. The velocity profiles are fitted to the
observed rotation curve data of high surface brightness and low surface
brightness galaxies. The brane-world model fits better the rotation curves with
asymptotically flat behaviour.
