Testing gravity with the Milky Way: Yukawa potential

We test a Yukawa correction to the Newtonian potential, making use of our own Galaxy - Milky Way as testbed. include free parameter strength and range dark matter profile parameters, compare several morphologies for bulge, gas, disk components, also using Bayesian model selection criteria. employ up-to-date datasets both visible (baryonic) component Way, tracers gravitational potential (the Rotation Curve). find that data are consistent with constrain coupling $\beta$ be negative $\lambda$ along curve $\lambda = a|\beta|^{c}$ $a (0.77 \pm 0.06)$ kpc $c -0.503\substack{+0.016 \\ -0.019}$.
