A Further Test of Lorentz Violation from the Rest-Frame Spectral Lags of Gamma-Ray Bursts
Jun-Jie Wei, Xue-Feng Wu
Lorentz invariance violation (LIV) can manifest itself by an energy-dependent vacuum dispersion of light, which leads to arrival-time differences of photons with different energies…
Constraining External Reverse Shock Physics of GRBs from ROTSE-III Limits
Xiao-Hong Cui, Yuan-Chuan Zou, Jun-Jie Wei +2
Assuming that the early optical emission is dominated by the external reverse shock (RS) in the standard model of gamma-ray bursts (GRBs), we intend to constrain RS models with the…
Model-independent Constraints on Cosmic Curvature and Opacity
Guo-Jian Wang, Jun-Jie Wei, Zheng-Xiang Li +2
In this paper, we propose to estimate the spatial curvature of the universe and the cosmic opacity in a model-independent way with expansion rate measurements, , and type Ia…
Strongly Lensed Gravitational Waves and Electromagnetic Signals as Powerful Cosmic Rulers
Jun-Jie Wei, Xue-Feng Wu
In this paper, we discuss the possibility of using strongly lensed gravitational waves (GWs) and their electromagnetic (EM) counterparts as powerful cosmic rulers. In the EM domain…
Constraining Anisotropic Lorentz Violation via the Spectral-Lag Transition of GRB 160625B
Jun-Jie Wei, Xue-Feng Wu, Bin-Bin Zhang +3
Violations of Lorentz invariance can lead to an energy-dependent vacuum dispersion of light, which results in arrival-time differences of photons arising with different energies fr…
New test of weak equivalence principle using polarized light from astrophysical events
Xue-Feng Wu, Jun-Jie Wei, Mi-Xiang Lan +3
Einstein's weak equivalence principle (WEP) states that any freely falling, uncharged test particle follows the same identical trajectory independent of its internal structure and…
