Abstract
- On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. We use this unique observation to probe an energy dependence of the speed of light in vacuo for photons as predicted by several quantum gravity models. Based on a set of assumptions on the possible intrinsic spectral and temporal evolution, we obtain competitive lower limits on the quadratic leading order of speed of light modification.<br />8 pages, 5 figures, Published in Physical Review Letters, Corresponding authors: Tomislav Terzi\'c (tterzic@phy.uniri.hr), Giacomo D'Amico (damico@mppmu.mpg.de), Daniel Kerszberg (dkerszberg@ifae.es), Cedric Perennes (perennes.cedric@gmail.com)
