Description
We demonstrate that the existence of a Noether symmetry in extended
theories of gravity gives rise to a further 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 relation, the rotation curve of gas-rich galaxies, and the
features of fundamental plane of ellipticals without the dark matter
hypothesis.
