# Resolution of dark matter problem in f(T) gravity

@article{Jamil2012ResolutionOD, title={Resolution of dark matter problem in f(T) gravity}, author={Mubasher Jamil and Davood Momeni and Ratbay Myrzakulov}, journal={The European Physical Journal C}, year={2012}, volume={72}, pages={1-7} }

In this paper, we attempt to resolve the dark matter problem in f(T) gravity. Specifically, from our model we successfully obtain the flat rotation curves of galaxies containing dark matter. Further, we obtain the density profile of dark matter in galaxies. Comparison of our analytical results shows that our torsion-based toy model for dark matter is in good agreement with empirical data-based models. It shows that we can address the dark matter as an effect of torsion of the space.
