# Galaxy rotation curves in modified gravity models

@article{deAlmeida2018GalaxyRC, title={Galaxy rotation curves in modified gravity models}, author={{\'A}lefe de Almeida and Luca Amendola and Viviana Niro}, journal={Journal of Cosmology and Astroparticle Physics}, year={2018}, volume={2018}, pages={012 - 012} }

In this work, we investigate the possibility that the galaxy rotation curves can be explained in the framework of modified gravity models that introduce a Yukawa term in the gravitational potential. We include dark matter and assume that the fifth-force couples differently to dark matter and to baryons. We aim at constraining the modified gravity parameters β and λ, that is, the strength and the range of the Yukawa fifth force, respectively, using a set of 40 galaxy rotation curves data from…
