ABSTRACT: The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field is applied to spiral and dwarf galaxy rotation curves. A new coupling function for the graviton redshift energy is described which improves the predicting power of the theory. Fits are made to the rotation curves of both high and low surface brightness galaxies. Furthermore, for some of the galaxies, as a demonstration of the versatility of the theory, it is shown how adjustments to the mass profile velocities can reduce the error of the fit of the predicted to the observed rotation curve, thus giving feedback to the observing process. The energy of the gravitational redshift of gravitons is a viable candidate for dark matter in galaxies.
