Constraints on the Primordial Black Hole Abundance through Scalar-Induced Gravitational Waves from Advanced LIGO and Virgo's First Three Observing Runs
Yang Jiang, Chen Yuan, Chong-Zhi Li +1
As a promising dark matter candidate, primordial black holes (PBHs) lighter than are supposed to have evaporated by today through Hawking radiation. This sc…

Gravitational Waves Induced by Scalar Perturbations with a Broken Power-law Peak
Chong-Zhi Li, Chen Yuan, Qing-guo Huang
We give an analytical approximation for the energy spectrum of the scalar-induced gravitational waves (SIGWs) generated by a broken power-law power spectrum, and find that both the…

Dualities between Scale Invariant and Magnitude Invariant Perturbation Spectra in Inflationary/Bouncing Cosmos
Chonghong Li, Yeuk-Kwan E. Cheung
We study cosmological perturbation spectra using the dynamical equations of gauge invariant perturbations with a generalized blue/red-shift term. Combined with the power-law index…
