Rotational velocity curves in the Milky Way as a test of modified gravity.

Galaxy rotation curves determined observationally out to a radius well beyond the galaxy cores can provide a critical test of modified gravity models without dark matter. The predicted rotational velocity curve obtained from scalar-vector-tensor gravity is in excellent agreement with data for the Milky Way without a dark matter halo, with a mass of 5 × 1010M☉. The velocity rotation curve predicted by modified Newtonian dynamics does not agree with the data. [ABSTRACT FROM AUTHOR]
