The availability of a new generation of instruments with capabilities to observe at high or very-high energies open an exciting perspective for GRB studies. The very large accessible energy band, including lower energy observations (soft X-rays down to optical and radio), will allow a reliable modeling of the GRB spectra both during the prompt phase and the afterglows. These information can...

Some models for quantum gravity (QG) violate Lorentz invariance (LIV) and predict an energy dependence of the speed of light, leading to a dispersion of high-energy gamma-ray signals that travel over cosmological distances. Limits on the dispersion from short-duration substructures observed in gamma-rays emitted by gamma-ray bursts (GRBs) at cosmological distances have provided interesting...
