Dark Matter from freeze-in and its inhomogeneities

Blog Article

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