Speakers: TaeHun Kim (KIAS)

Primordial black holes (PBHs), hypothesized to have largely been produced in the early Universe, span a broad mass range and offer rich cosmological and astrophysical implications. Among them, there has been a recent growing interest in the evaporating PBHs, looking for the cosmological consequences of their past existence and observable signatures. In this talk, I will provide a brief overview of PBHs and the physics of their evaporation. Then, I will introduce two of my recent works on evaporating PBHs, about their reformation and isocurvature generation. These examples are just a fraction of the phenomenological side of the rich physics of PBHs.
