Numerical studies of inelastic dark matter cosmology

There are indications that the LambdaCDM paradigm may face "small-scale" problems, which would mean its incompleteness. One of a promising DM model is that with inelastic interactions in the dark sector. Here we explore the model with cosmological simulations with baryons using state-of-the-art baryonic feedback model. We discuss the effectiveness of the inelastic DM model and the interplay between DM and baryonic effects.
