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 invariance. Fermi Large Area Telescope (LAT) observations of gamma-ray bursts (GRBs) are sensitive probes of Lorentz invariance, via studies of energy-dependent timing shifts in their rapidly-varying photon emissions. In this paper we analyze the Fermi-LAT measurements of high-energy gamma rays from… 
Search for Lorentz Invariance Violation from stacked Gamma-Ray Burst spectral lag data
A number of works have claimed detections of a turn-over in the spectral lag data for individual Gamma-Ray Bursts (GRBs), caused by an energy-dependent speed of light, which could be a possible

Lorentz invariance violations (LIV) can yield vacuum birefringence, which results in an energy-dependent rotation of the polarization vector of linearly polarized emission from astrophysical sources.
Prospective Annual Detection Rate of High-energy Gamma-Ray Bursts with LHAASO-WCDA
The γ-ray bursts (GRBs) are the most violent explosion events in the universe ever since the Big Bang and can be served as the high redshift probes for cosmological study. Particularly, the
Testing fundamental physics with astrophysical transients
Explosive astrophysical transients at cosmological distances can be used to place precision tests of the basic assumptions of relativity theory, such as Lorentz invariance, the photon zero-mass
Light speed variation with brane/string-inspired space-time foam
Neutrino signals of lightcone fluctuations resulting from fluctuating spacetime
One of the most common expectations of a quantum theory of gravity is that space-time is uncertain or fluctuating at microscopic scales, making it a stochastic medium for particle propagation.
Phenomenological Effects of CPT and Lorentz Invariance Violation in Particle and Astroparticle Physics
TLDR
The state of art for astroparticle physics, quantum field theory, quantum gravity, and neutrino beams are discussed, with some interesting new proposals, both from a theoretical and phenomenological point of view.
Light speed variation from gamma ray bursts: criteria for low energy photons
We examine a method to detect the light speed variation from gamma ray burst data observed by the Fermi Gamma-ray Space Telescope (FGST). We suggest new criteria to determine the characteristic time
Constraints on Lorentz Invariance Violation with Multiwavelength Polarized Astrophysical Sources
Possible violations of Lorentz invariance (LIV) can produce vacuum birefringence, which results in a frequency-dependent rotation of the polarization plane of linearly polarized light from distant

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
STRING QUANTUM GRAVITY, LORENTZ-INVARIANCE VIOLATION AND GAMMA-RAY ASTRONOMY
In the first part of the review, I discuss ways of obtaining Lorentz-Invariance-Violating (LIV) space-time foam in the modern context of string theory, involving brane world scenarios. The foamy

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
Bounds on spectral dispersion from Fermi-detected gamma ray bursts.
TLDR
It is shown that significant photon bunches in GRB 090510A, possibly classic GRB pulses, are remarkably brief, an order of magnitude shorter in duration than any previously claimed temporal feature in this energy range, suggesting that spacetime is smooth at energies near and slightly above the Planck mass.
