Galaxy Rotation Curves in Covariant Ho？ava-Lifshitz Gravity

Using the multiplicity of solutions for the projectable case of the covariant extension of Ho？ava-Lifshitz gravity, we show that an appropriate choice for the auxiliary field allows for an effective description of galaxy rotation curves. This description is based on static and spherically symmetric solutions of covariant Ho？ava-Lifshitz gravity and does not require Dark Matter.
