High-energy scalarons in R^{2} gravity as a model for Dark Matter in galaxies

Understand

We show that in the framework of R^{2} gravity and in the linearized approach it is possible to obtain spherically symmetric stationary states that can be used as a model for galaxies.

• The model can also help to have a better understanding on the theoretical basis of Einstein-Vlasov systems.
• Specifically, we discuss, in the linearized R^{2} gravity, the solutions of a Klein-Gordon equation for the spacetime curvature.
• Such solutions describe high energy scalarons, a field that in the context of galactic dynamics can be interpreted like the no-light-emitting galactic component.
