Rotational Velocity Curves in the Milky Way as a Test of Modified Gravity

Abstract

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 (STVG or MOG) is in excellent agreement with data for the Milky Way without a dark matter halo, with a mass of $5\times 10^{10}{M}_{\odot }$. The velocity rotation curve predicted by modified Newtonian Dynamics (MOND) does not agree with the data.
