LORENTZ VIOLATION EFFECTS ON ASTROPHYSICAL PROPAGATION OF VERY HIGH ENERGY PHOTONS
Lorentz violation (LV) is predicted by some quantum gravity (QG) candidates, wherein the canonical energy–momentum dispersion relation, E2 = p2+m2, is modified. Consequently, new phenomena beyond the
Robust constraint on Lorentz violation using Fermi-LAT gamma-ray burst data
Models of quantum gravity suggest that the vacuum should be regarded as a medium with quantum structure that may have non-trivial effects on photon propagation, including the violation of Lorentz
Lorentz violation from gamma-ray burst neutrinos
The Lorentz violation (LV) effect of ultra-relativistic particles can be tested by gamma-ray burst (GRB) neutrinos and photons. The IceCube Collaboration has observed plenty of ultra-high energy
Ultrahigh-energy photons from LHAASO as probes of Lorentz symmetry violations
The Large High Altitude Air Shower Observatory (LHAASO) is one of the most sensitive gammaray detector arrays currently operating at TeV and PeV energies. Recently the LHAASO experiment detected
Light speed variation from gamma-ray bursts
Constraints on quantum gravity and the photon mass from gamma ray bursts
Lorentz Invariance Violation in Quantum Gravity (QG) models or a non-zero photon mass, mγ , would lead to an energy-dependent propagation speed for photons, such that photons of different energies
Regularity of high energy photon events from gamma ray bursts
The effect of Quantum Gravity (QG) may bring a tiny light speed variation as $v(E)=c(1-E/E_{\rm LV})$, where $E$ is the photon energy and $E_{\rm LV}$ is a Lorentz violation scale. A remarkable
A Further Test of Lorentz Violation from the Rest-Frame Spectral Lags of Gamma-Ray Bursts
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 originating from
Dispersion of light traveling through the interstellar space, induced and intrinsic Lorentz invariance violation
Theoretical models and experimental observations suggest that gamma-ray bursts (GRB) and high-energy neutrino bursts travelling through the interstellar space may reach the Earth at different speeds.
Limits on the Neutrino Velocity, Lorentz Invariance, and the Weak Equivalence Principle with TeV Neutrinos from Gamma-Ray Bursts
Five TeV neutrino events weakly correlated with five gamma-ray bursts (GRBs) were detected recently by IceCube. This work is an attempt to show that if the GRB identifications are verified, the

Prospects for constraining quantum gravity dispersion with near term observations
We discuss the prospects for bounding and perhaps even measuring quantum gravity effects on the dispersion of light using the highest-energy photons produced in gamma-ray bursts (GRBs) measured by
Tests of quantum gravity from observations of γ-ray bursts
The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. Here
A limit on the variation of the speed of light arising from quantum gravity effects
TLDR
The detection of emission up to ∼31 GeV from the distant and short GRB, and no evidence for the violation of Lorentz invariance is found, which disfavour quantum-gravity theories in which the quantum nature of space–time on a very small scale linearly alters the speed of light.
Limits to Quantum Gravity Effects on Energy Dependence of the Speed of Light from Observations of TeV Flares in Active Galaxies
We have used data from a TeV {gamma} -ray flare associated with the active galaxy Markarian 421 to place bounds on the possible energy dependence of the speed of light in the context of an effective
Constraints on Lorentz invariance violation from gamma-ray burst GRB090510
We obtain modified dispersion relations by requiring the vanishing of determinant of inverse of modified photon propagators in Lorentz invariance violation (LIV) theory. Inspired by these dispersion
A Search in Gamma-Ray Burst Data for Nonconstancy of the Velocity of Light
We discuss possible tests of the constancy of the velocity of light using distant astrophysical sources such as gamma-ray bursters (GRBs), active galactic nuclei (AGNs), and pulsars. This speculative
Lorentz violation for photons and ultrahigh-energy cosmic rays.
TLDR
It is shown that first and second order terms of size |xi1|>orsimilar10(-14) and xi2<orsimilar-10(-6), respectively, would lead to a photon component in cosmic rays above 10(19) eV that should already have been detected, if corresponding terms for e+/- are significantly smaller.
Quantum-gravity analysis of gamma-ray bursts using wavelets
In some models of quantum gravity, space-time is thought to have a foamy structure with non-trivial optical prop- erties. We probe the possibility that photons propagating in vacuum may exhibit a
