Primordial Black Hole Formation from Type II Fluctuations with Primordial Non-Gaussianity

Masaaki Shimada, Albert Escrivá, Daiki Saito +2

This study investigates the formation of primordial black holes (PBHs) resulting from the collapse of adiabatic fluctuations with large amplitudes and non-Gaussianity. Ref. \cite{U…
