$R^n$ gravity is kicking and alive: the cases of Orion and NGC 3198
  We analyzed the Rotation Curves of two crucial objects, the Dwarf galaxy
Orion and the low luminosity Spiral NGC 3198, in the framework of $R^n$
gravity. We surprisingly found that the no DM power-law f(R) case fits them
well, performing much better than $\Lambda$CDM Dark Matter halo models. The
level of this unexpected success can be a boost for $R^n$ gravity.
