Abstract

We address the homogeneous in space and time G"odel-type metrics within the cubic Galileon theory, a particular class of generalized Galileon theories. We check the consistency of such space-times for a physically well-motivated matter content, namely, a perfect fluid and an electromagnetic field. In this scenario, we find that the admissible solutions impose constraints on the constant couplings (c_is) of the cubic Galileon theory to ensure the consistency. Also, we show the existence of a vacuum completely causal solution.
