New Constraints on Lorentz Invariance Violation at High Redshifts from Multiband of GRBs
Mingyue Chen, Jun Tian, Yu Pan +2
In the gravity quantum theory, the quantization of spacetime may lead to the modification of the dispersion relation between the energy and the momentum and the Lorentz invariance…
Model-independent way to determine the Hubble constant and the curvature from phase shift of gravitational waves with DECIGO
Tonghua Liu, Shuo Cao, Marek Biesiada +2
In this Letter, we propose a model-independent method to determine the Hubble constant and curvature simultaneously taking advantage of the possibilities of future space-borne grav…
A robust test of general relativity at the galactic scales by combining strong lensing systems and gravitational wave standard sirens
Tonghua Liu, Marek Biesiada, Shuxun Tian +1
The measurement of the parametrized post-Newtonian parameter is a robust test of general relativity (GR). In some modified theories of gravity, may ev…
Multiple measurements on the cosmic curvature using Gaussian process regression without calibration and a cosmological model
Xiaolong Gong, Yifei Xu, Tonghua Liu +4
In this letter, we propose an improved cosmological model-independent method to measure cosmic curvature, combining the recent measurements of transverse and line-of-sight directio…
Simultaneous measurements on cosmic curvature and opacity using latest HII regions and observations
Ying Yang, Tonghua Liu, Jiayuan Huang +3
The different spatial curvatures of the universe affect the measurement of cosmological distances, which may also contribute to explaining the observed dimming of type Ia supernova…
Distinguishing CDM from evolving dark energy with the future gravitational-wave space-borne detector DECIGO
Yuting Liu, Shuo Cao, Xiaogang Zheng +3
The two point diagnostics was proposed as a litmus test of CDM model and measurements of cosmic expansion rate have been extensively used to perform this…
