Unveiling Primordial Black Hole Relics Through Induced Gravitational Waves
Misao Sasaki, Jianing Wang
Black hole relics are of significant interest in cosmology and theoretical physics. In this work, we consider tiny primordial black holes (PBHs) ( $M_{\text {PBH }} \lesssim 10^7 \…

Revisiting the Ultraviolet Tail of the Primordial Gravitational Wave
Shi Pi, Misao Sasaki, Ao Wang +1
High-frequency primordial gravitational waves (PGWs) with wave numbers larger than the Hubble parameter at the end of inflation are originated from the ultraviolet (UV) modes, whic…
