# Fitting rotation curves of galaxies by de Rham-Gabadadze-Tolley massive gravity

@article{Panpanich2018FittingRC, title={Fitting rotation curves of galaxies by de Rham-Gabadadze-Tolley massive gravity}, author={Sirachak Panpanich and Piyabut Burikham}, journal={Physical Review D}, year={2018} }

We investigate the effects of massive gravitons on the rotation curves of the Milky Way, spiral galaxies, and low surface brightness (LSB) galaxies. Using a simple de Rham, Gabadadze, and Tolley (dRGT) massive gravity model, we find a static spherically symmetric metric and a modified Tolman-Oppenheimer-Volkoff (TOV) equation. The dRGT nonlinear graviton interactions generate density and pressures, which behave like dark energy that can mimic the gravitational effects of a dark matter halo. We…
