Primordial black hole formation in chiral cosmological models E. O. Pozdeeva |
|||
|
Abstract: We consider the chiral cosmological models with two scalar fields inspired by modified gravity. For some values of models parameters, we reproduce appropriate values for inflationary parameters. During inflation we get ultra-slow-roll regime corresponding to the nearly-inflection point of the potential leading to increasing energy density perturbations and primordial black hole formation in the radiation dominant stage.
