Cause of spiral galaxy rotation rates: a massive graviton.

PESTANA J.L.G. and ECKHARDT D.H.

Abstract (from CDS):

We attribute the observed rotational velocity profiles of spiral galaxy disks to a combination of Newtonian and exponential gravitational potentials. We offer a novel, yet perfectly plausible, Lagrangian from which the exponential potential is derived. The exponential potential is defined by two universal constants (corresponding to a coupling constant and a graviton mass) that we determine from our sample of 12 THINGS disks. All velocity profile fits are excellent.
