QG with GRBs - Testing Lorentz invariance with gamma-ray bursts
T. Piran

Abstract

Lorentz invariance violation (LIV) arises in various quantum gravity theories. This could possibly take place at very high energies that are not accessible on earth. It was realized in recent years that astronomical observations can help to explore set limits on this phenomenon.

Gamma-Ray Bursts (GRBs) are short and intense cosmological bursts of gamma-rays, with energies ranging from tens of keV up to GeV and possibly higher. They are the brightest electromagnetic objects in the Universe. Remarkably they can be used to set the current best limits on LIV.

In this lecture I review, first, current observations and our understanding of GRBs and then I turn to show how they can be used to explore LIV.
