Galactic Structures from Gravitational Radii

We demonstrate that the existence of a Noether symmetry in f ( R ) theories of gravity gives rise to an additional gravitational radius, besides the standard Schwarzschild one, determining the dynamics at galactic scales. By this feature, it is possible to explain the baryonic Tully-Fisher r...
