Gravitational wave cosmology
Ligong Bian, Rong-Gen Cai, Yu-Qi Dong +18
Gravitational waves (GWs) originating from cosmological sources offer direct insights into the physics of the primordial Universe, the fundamental nature of gravity, and the cosmic…
Generic effective sources for first-order in mass-ratio gravitational self-force calculations in Schwarzschild spacetime
Chao Zhang, Rong-gen Cai, Guoyang Fu +3
The numerical calculation of gravitational self-force in extreme mass ratio inspiral systems is fundamentally challenging due to the singular nature of point-particle sources. To o…
Null tests with Gaussian Process
Shengqing Gao, Qing Gao, Yungui Gong +1
We investigate the null tests of spatial flatness and the flat CDM model using the Baryon Acoustic Oscillation (BAO) data measured by the Dark Energy Spectroscopic Instrument (D…
On the evidence of dynamical dark energy
Qing Gao, Zhiqian Peng, Shengqing Gao +1
To elucidate the robustness of the baryon acoustic oscillation (BAO) data measured by the Dark Energy Spectroscopic Instrument (DESI) in capturing the dynamical behavior of dark en…
On the duality in constant-roll inflation
Yue Wang, Qing Gao, Shengqing Gao +1
There is a duality in the observables , and the inflaton potential between large and small for the constant-roll inflation if the slow-roll parameter is neglig…
Primordial black holes and scalar-induced gravitational waves from the polynomial attractor model
Zhongkai Wang, Shengqing Gao, Yungui Gong +1
Primordial black holes (PBHs) generated in the early Universe are considered as one of the candidates for dark matter. To produce PBHs with sufficient abundance, the primordial sca…
Probing the equation of state of neutron stars with captured primordial black holes
Qing Gao, Ning Dai, Yungui Gong +3
Gravitational waves (GWs) from primordial black holes (PBHs) inspiraling within neutron stars (NSs) -- should they exist -- are detectable by ground-based detectors and offer a uni…
