Detecting new fundamental fields with Pulsar Timing Arrays
Chao Zhang, Ning Dai, Qing Gao +3
Strong evidence of the existence of the Stochastic Gravitational-Wave Background (SGWB) has been reported by the NANOGrav, PPTA, EPTA and CPTA collaborations. The Bayesian posterio…
Sky localization of space-based detectors with time-delay interferometry
Tong Jiang, Yungui Gong, Xuchen Lu
The accurate sky localization of gravitational wave (GW) sources is an important scientific goal for space-based GW detectors. The main differences between future space-based GW de…
Polarizations of Gravitational Waves in the Bumblebee Gravity Model
Dicong Liang, Rui Xu, Xuchen Lu +1
Lorentz violation modifies the dispersion relation of gravitational waves (GWs), and induces birefringence and anisotropy in propagation. Our study shows that Lorentz violation can…
Supernova calibration by gravitational wave
Xuchen Lu, Yungui Gong
Hubble tension is one of the most important problems in cosmology. Although the local measurements on the Hubble constant with Type Ia supernovae (SNe Ia) are independent of cosmol…
Strong gravitational field time delay for photons coupled to Weyl tensor in a Schwarzschild black hole
Xu Lu, Feng-Wei Yang, Yi Xie
We analyse strong gravitational field time delay for photons coupled to the Weyl tensor in a Schwarzschild black hole. By making use of the method of strong deflection limit, we fi…
