Radial acceleration relation from symmetron fifth forces

Burrage, Clare; Copeland, Edmund J.; Millington, Peter

Abstract

We show that the radial acceleration relation for rotationally supported galaxies may be explained, in the absence of cold dark matter, by a nonminimally coupled scalar field, whose fifth forces are partially screened on galactic scales by the symmetron mechanism. In addition, we show that sufficient energy is stored in the symmetron field to explain the dynamic stability of galactic disks.
