Projected Constraints on Primordial Black Holes from Scalar-Induced Gravitational Waves with Taiji
Yang Jiang, Chen Yuan, Qing-Guo Huang
Scalar-induced gravitational waves (SIGWs) provide a direct probe of the enhanced primordial curvature perturbations that may also produce primordial black holes (PBHs). We forecas…
Estimating galactic foreground with the population of resolved galactic binaries
Yang Jiang, Qing-Guo Huang
The stochastic gravitational wave background (SGWB) in the millihertz band constitutes a primary science target for future space-based interferometers. The detection of such a sign…
One-Loop Tensor Power Spectrum from a Non-Canonical Spectator Field during Inflation
Zhe Li, Chen Yuan, Qing-Guo Huang
We compute the full one-loop corrections to the primordial tensor power spectrum in an inflationary scenario with a {non-canonical spectator field}, using the in-in formalism. We d…
Whispers from the Early Universe: The Ringdown of Primordial Black Holes
Chen Yuan, Zhen Zhong, Qing-Guo Huang
We investigate the stochastic gravitational wave background (SGWB) generated by the ringdown phase of primordial black holes (PBHs) formed in the early universe. As the ringdown si…
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…
