Angular power spectrum of induced gravitational waves: breaking model and parameter degeneracies in PTA observations
Peng-Yu Wu, Di Wu, Jing-Zhi Zhou
Large primordial curvature and tensor perturbations on small scales can generate second-order tensor-scalar induced gravitational waves (TSIGWs) through scalar-scalar, tensor-scala…
Inflation on the lattice: scalar Gauss-Bonnet single field inflation
Fei-Yu Chen, Jing-Zhi Zhou, Zhi-Chao Li +1
We use lattice methods to study inflation in the scalar Gauss-Bonnet (SGB) gravity theory. We focus on the ultra-slow-roll scenario with the peak frequency falls into the PTA band.…
Scalar induced gravitational waves as probes of dark QCD
Wan-Zhe Feng, Ao Li, Jing-Zhi Zhou
We investigate scalar induced gravitational waves (SIGWs) as probes of a dark QCD crossover. Motivated by twin Higgs and asymmetric twin baryon dark matter scenarios, we consider a…
Tensor induced gravitational waves
Fei-Yu Chen, Jing-Zhi Zhou, Di Wu +2
Primordial gravitational waves on small scales are not tightly constrained by current cosmological observations, which allows for the possibility of large amplitudes at small scale…
Probing small-scale primordial power spectra with induced gravitational waves
Di Wu, Zhi-Chao Li, Peng-Yu Wu +2
Large-scale primordial perturbations have been well constrained by current cosmological observations, but the properties of small-scale perturbations remain elusive. This study foc…
Cosmological constraints on small-scale primordial non-Gaussianity
Jing-Zhi Zhou, Zhi-Chao Li, Di Wu
In contrast to the large-scale primordial power spectrum and primordial non-Gaussianity , which are strictly constrained, the small-scale $\math…
