Radial acceleration relation from symmetron fifth forces
  We show that the radial acceleration relation for rotationally-supported
galaxies may be explained, in the absence of cold dark matter, by a
non-minimally 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.
