Study of Lorentz violation in INTEGRAL gamma-ray bursts

Steiner, Frank; Produit, Nicolas; Lamon, Raphael

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 and arrival time of every detected single photon, which enhances the precision of the time resolution. We present a new method for seeking time lags …
