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 fluid.We Cologne find that Dark Matter inherits the Standard Model adiabatic inhomogeneities on the cosmological scales probed by current Heat Pump observations, that were super-horizon during freeze-in.Thereby, freeze-in satisfies the bounds on iso-curvature perturbations.
