A Model of f (R) Gravity as an Alternative for Dark Matter in Spiral Galaxies

Solmaz Asgari, Reza Saffari

Abstract


In this paper we study consistent solutions of spherically symmetric space in metric f (R) gravity theory. Here
we inversely obtain a generic action from metric solutions that describe flat rotation curves in spiral galaxies
without dark matter. Then we show that obtained solutions are in conformity with Tully-Fisher relation and
modified Newtonian dynamics, which are two strong constraints in justification of flat rotation curves in spiral
galaxies.
