Dark Matter from freeze-in and its inhomogeneities

Abstract We consider generic freeze-in processes for generation of Dark Matter, together with the consequent re-thermalization of the Standard Model read more fluid.We find that Dark Matter inherits the Standard Model guerlain ideal cologne adiabatic inhomogeneities on the cosmological scales probed by current observations, that were super-horizon during freeze-in.Thereby, freeze-in satisfies the bounds on iso-curvature perturbations.
