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 from a distant source would arrive at different times, even if they were emitted simultaneously. By developing source-by-source, Monte Carlo-based forward models for such time delays from Gamma Ray Bursts, and marginalising over empirical noise models describing other contributions to the time delay…

A search for the variation of speed of light using galaxy cluster gas mass fraction measurements
In this paper, we implement a new method to test the invariance of the speed of light (c) as a function of redshift, by combining the measurements of galaxy cluster gas mass fraction, H(z) from


Model-independent Constraints on Lorentz Invariance Violation: Implication from Updated Gamma-Ray Burst Observations
Astrophysical observations provide a unique opportunity to test possible signatures of Lorentz Invariance Violation (LIV), due to the high energies and long distances involved. In quantum theory of
Combined limit on the photon mass with nine localized fast radio bursts
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 originating from a
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
Robust limits on photon mass from statistical samples of extragalactic radio pulsars
The photon zero-mass hypothesis has been investigated for a long time using the frequency-dependent time delays of radio emissions from astrophysical sources. However, the search for a rest mass of
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
Constraining Anisotropic Lorentz Violation via the Spectral-Lag Transition of GRB 160625B
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 from a given
Study of Lorentz violation in INTEGRAL gamma-ray bursts
We search for possible time lags caused by quantum gravitational effects using gamma-ray bursts (GRBs) detected by INTEGRAL. The advantage of this satellite is that we have at our disposal the energy
