Modified gravity theories and dark matter models tested by galactic rotation curves

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

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.
