- Аннотация: We study the possibility to constrain deviations from Lorentz invariance in dark matter (DM) with cosmological observations. The homogeneous expansion of the Universe with Lorentz violating (LV) DM is found to be practically indistinguishable from the standard ΛCDM cosmology. On the other hand, the evolution of the cosmological perturbations significantly differs from the standard case. We discuss, at which level this type of deviations from Lorentz invariance is constrained by the present-day and upcoming cosmological observations.
