Effect of inelastic dark matter on Lyman-alpha forrest

There is mounting evidence that the LambdaCDM paradigm may be too simplistic and incomplete. A natural extension of the CDM is to allow for interactions --- both elastic and inelastic --- in the dark sector. Here we explore this possibility via cosmological simulations with baryons using state-of-the-art baryonic feedback model. In particular, we study the implications for tLyman-alfa forrest observations. We discuss the interplay between DM and baryonic effects.
