Simultaneous determination of Hubble constant and cosmic baryon density: Forecasts for the synergy between FRBs and emerging probes
Peng-Ju Wu, Bo-Yang Zhang, Ji-Guo Zhang +3
Two of the most pressing challenges in cosmology are the persistent discrepancy in measurements of the Hubble constant, referred to as the Hubble tension, and the deficit of baryon…

Constraining parity and Lorentz violations in gravity with future ground- and space-based gravitational wave detectors
Bo-Yang Zhang, Tao Zhu, Jian-Ming Yan +2
The future ground- and space-based gravitational wave (GW) detectors offer unprecedented opportunities to test general relativity (GR) with greater precision. In this work, we inve…

Forecasts for Constraining Lorentz-violating Damping of Gravitational Waves from Compact Binary Inspirals
Bo-Yang Zhang, Tao Zhu, Jing-Fei Zhang +1
Violation of Lorentz symmetry can result in two distinct effects in the propagation of the gravitational waves (GWs). One is a modified dispersion relation and another is a frequen…
