Black holes from a Higgs-like field in the radiation era
Ethan Milligan, Luis E. Padilla, David J. Mulryne
Light spectator fields during inflation can acquire superhorizon fluctuations that cross a potential barrier between positive and negative regions of their potential. Motivated by…
Discrete self-similarity imprints on primordial-black-hole mass functions
Luis E. Padilla, Tomohiro Harada, Hayami Iizuka
We study how discrete self-similarity (DSS) in the critical behavior of scalar-field collapse is imprinted on primordial-black-hole (PBH) mass functions. Using the DSS-modulated cr…
Cosmological discrete self-similarity in primordial black hole formation
Luis E. Padilla, Tomohiro Harada, Ethan Milligan +1
We demonstrate that discrete self-similarity (DSS), originally discovered in the collapse of a massless scalar field in an asymptotically flat system, survives in primordial black…
