Lorentz symmetry is a fundamental pillar of General Relativity and Particle Physics. Nonetheless, certain theories of quantum gravity involve some degree of Lorenz violation which may have significant consequences on all scale. It is hence worthwhile to explore the observable signatures of Lorentz violations on the dynamics of the low energy spectrum of the theory. I will consider the case of a Lorentz violating vector field acting on the dark matter component of a satellite galaxy orbiting in a host halo and discuss the key observational signatures such as modifications to the line of sight velocity dispersion, mass profiles and shapes of satellites.
