Lattice study of primordial black hole formation in bumpy axion inflation
Masahiro Kawasaki, Kai Murai, Shunsuke Tsuchida
We study primordial black hole (PBH) formation in axion inflation using lattice simulations. In axion inflation with a bumpy potential, the curvature perturbations ca…
Merger rate of initially clustered primordial black holes for the two-body channel
Kentaro Kasai, Masahiro Kawasaki, Kai Murai +1
Primordial black holes (PBHs) may form an initially clustered population depending on their production mechanism. Motivated by binary black-hole merger events observed by gravitati…
Microlensing events and primordial black holes in the axionlike curvaton model
Kentaro Kasai, Masahiro Kawasaki, Kai Murai +1
Recently, Subaru Hyper Suprime-Cam (HSC) observations found 12 candidates for microlensing events. These events can be explained by primordial black holes (PBHs) with masses of $10…
