A comparison between repeating bursts of FRB 121102 and giant pulses from Crab pulsar and its applications
Fen Lyu, Yan-Zhi Meng, Zhen-Fan Tang +6
There are some similarities between bursts of repeating fast radio bursts (FRBs) and giant pulses (GPs) of pulsars. To explore possible relations between them, we study the cumulat…
Lorentz Invariance Violation Limits from the Spectral Lag Transition of GRB~190114C
Shen-Shi Du, Lin Lan, Jun-Jie Wei +8
The spectral lags of gamma-ray bursts (GRBs) have been viewed as the most promising probes of the possible violations of Lorentz invariance (LIV). However, these constraints usuall…
Self-organized Criticality in Multi-pulse Gamma-Ray Bursts
Fen Lyu, Ya-Ping Li, Shu-Jin Hou +3
The variability in multi-pulse gamma-ray bursts (GRBs) may help to reveal the mechanism of underlying processes from the central engine. To investigate whether the self-organized c…
Constraining Einstein's Equivalence Principle With Multi-Wavelength Polarized astrophysical Sources
Shuang-Xi Yi, Yuan-Chuan Zou, Jun-Jie Wei +1
The observed time delays between photons with different circular polarizations from an astrophysical object provide a new, interesting way of testing the Einstein Equivalence Princ…
Testing the Weak Equivalence Principle and Lorentz Invariance with Multiwavelength Polarization Observations of GRB Optical Afterglows
Jun-Jie Wei, Xue-Feng Wu
Violations of both the weak equivalence principle (WEP) and Lorentz invariance can produce vacuum birefringence, which leads to an energy-dependent rotation of the polarization vec…
Combined Limit on the Photon Mass with Nine Localized Fast Radio Bursts
Jun-Jie Wei, Xue-Feng Wu
A nonzero-mass hypothesis for the photon can produces a frequency-dependent dispersion of light, which results in arrival-time differences of photons with different frequencies ori…
