Two-Dimensional Pulsar Distance Inference from Nanohertz Gravitational Waves
Si-Ren Xiao, Ji-Yu Song, Yue Shao +3
Pulsar timing arrays (PTAs) are limited in localizing nanohertz continuous gravitational waves (CGWs) by uncertainties in pulsar distances. We introduce a method to infer pulsar di…
Tests of general relativity at the fourth post-Newtonian order with GW230627 and GW250114
Xi-Min Liang, Yuan-Zhu Wang, Tao Zhu +2
Gravitational wave (GW) observations provide an unprecedented laboratory for testing general relativity (GR) in the strong-field, highly dynamic, and relativistic regimes. Within t…
Synergy between CSST and third-generation gravitational-wave detectors: Inferring cosmological parameters using cross-correlation of dark sirens and galaxies
Ya-Nan Du, Ji-Yu Song, Yichao Li +4
Gravitational-wave (GW) events are generally believed to originate in galaxies and can thus serve, like galaxies, as tracers of the universe's large-scale structure. In GW observat…
Bounding the number of spacetime dimensions from precessing black hole binaries with the third-generation gravitational-wave detectors
Xu-Jie Zhu, Ji-Yu Song, Tao Zhu +1
In the theories with extra dimensions, gravitational waves can leak into extra dimensions, resulting in a reduction in the amplitude of the observed gravitational waves. Such an ef…
Multi-messenger standard-siren cosmology for third-generation gravitational-wave detectors: forecasts considering observations of gamma-ray bursts and kilonovae
Tao Han, Jing-Fei Zhang, Xin Zhang
In the third-generation (3G) gravitational-wave (GW) detector era, GW multi-messenger observations for binary neutron star merger events can exert great impacts on exploring the co…
Prospects for searching for sterile neutrinos with gravitational wave and -ray burst joint observations
Lu Feng, Tao Han, Jing-Fei Zhang +1
Sterile neutrinos can influence the evolution of the universe, and thus cosmological observations can be used to detect them. Future gravitational wave (GW) observations can precis…
