Description

Lorentz invariance violation (LV) can be examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the Lorentz violation energy scale as $E_{\rm LV} \simeq 3.60 \times 10^{17}$~GeV using Fermi Gamma-ray Space Telescope (FGST) data. We update the time delay model and reaffirm these findings with new observations.
