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 find that Dark here Matter inherits the Standard Model adiabatic inhomogeneities on the cosmological scales probed by current 730 sunken lake road observations, that were super-horizon during freeze-in.Thereby, freeze-in satisfies the bounds on iso-curvature perturbations.
