Dark Matter from freeze-in and its inhomogeneities

Blog Article

Abstract We consider generic freeze-in processes for generation of Dark Matter, together with the consequent re-thermalization of the Standard Model ut solution gel for cats fluid.We find that Dark Matter inherits the Standard Model adiabatic inhomogeneities on the cosmological scales probed by current observations, that were super-horizon during rab valiance jakke herre freeze-in.Thereby, freeze-in satisfies the bounds on iso-curvature perturbations.
