Description

MAGIC is a stereoscopic system of two Imaging Atmospheric Cherenkov Telescopes located on the Canary island of La Palma that detects gamma rays from 30 GeV to 50 TeV. Observations by MAGIC allow to probe, among others, various fundamental physics topics. One of these topics is the search for Lorentz Invariance Violation (LIV) effect in the attempt to build a quantum theory of gravity. The observation and detection of the gamma-ray burst GRB190114C by MAGIC on the night of the 14th January 2019 openned a new window for LIV search using gamma-ray bursts detected at TeV energies. In this talk, I will report on the detection of GRB1910114C and on the constraints on LIV derived from this observation. I will also give a glimpse of what such an event would look like with future instruments such as the Large Size Telescopes of the Cherenkov Telescope Array, the first one of which being currently commissioned in La Palma.
