COSMOS: A numerical relativity code specialized for PBH formation
Chul-Moon Yoo, Hirotada Okawa, Albert Escrivà +7
Primordial black holes (PBHs) are black holes generated in the early universe without having gone through stellar evolution. In the standard formation process, PBHs are formed from…
Primordial black hole formation from a type II perturbation in the absence and presence of pressure
Koichiro Uehara, Albert Escrivà, Tomohiro Harada +2
We investigate primordial black holes (PBHs) formed from extremely large amplitudes of primordial curvature fluctuations, classified as type II. Type II fluctuations differ from ty…
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…
Numerical simulation of type II primordial black hole formation
Koichiro Uehara, Albert Escrivà, Tomohiro Harada +2
This study investigates the formation of type II primordial black holes (PBHs) resulting from extremely large amplitudes of initial fluctuations in a radiation-dominated universe.…
