Primordial black holes and gravitational waves from parametric amplification of curvature perturbations
Rong-Gen Cai, Zong-Kuan Guo, Jing Liu +2
We investigate a new mechanism to create large curvature perturbations on small scales due to parameter resonance in a single-field inflationary model with a small periodic structu…
Mass bound for primordial black hole from trans-Planckian censorship conjecture
Rong-Gen Cai, Shao-Jiang Wang
The recently proposed trans-Planckian censorship conjecture (TCC) imposes a strong constraint on the inflationary Hubble scale, of which the upper bound could be largely relaxed by…
Universal infrared scaling of gravitational wave background spectra
Rong-Gen Cai, Shi Pi, Misao Sasaki
We study the general infrared behavior of the power spectrum of a stochastic gravitational wave background produced by stress tensor in the form bilinear in certain dynamical degre…
Primordial Black Holes from Cosmic Domain Walls
Jing Liu, Zong-Kuan Guo, Rong-Gen Cai
We investigate the formation of primordial black holes (PBHs) from the collapse of spherically symmetric domain wall bubbles, which spontaneously nucleate via quantum tunneling dur…
Pulsar Timing Array Constraints on the Induced Gravitational Waves
Rong-Gen Cai, Shi Pi, Shao-Jiang Wang +1
If the black holes detected by LIGO/VIRGO are primordial black holes (PBHs) sourcing from a large primordial curvature perturbation on small scales, the corresponding induced gravi…
Probing cosmic anisotropy with GW/FRB as upgraded standard sirens
Rong-Gen Cai, Tong-Bo Liu, Shao-Jiang Wang +1
Recently it was shown that cosmic anisotropy can be well tested using either standard siren measurement of luminosity distance from gravitational-wave (GW) observ…
