The latest data of the Planck satellite, combined with other observations of the large-scale structure of the Universe, is only compatible with very small deviations from the minimal standard cosmological model (LambdaCDM). Still, in these small deviations, there would be room for interesting effects related to particle physics models. I will focus on several Dark Matter properties that can be constrained by current data (annihilation, decay, non-weak interactions, velocity dispersion) and that may be tested with the next generation of cosmological surveys.
