Description
Gamma-ray bursts (GRBs) are one of the most energetic explosions in the universe. GRBs still have various unknown aspects such as gamma-ray emission processes and jet launching mechanisms.
Gamma-ray observations on GRBs have been performed mainly by satellite telescopes, however photon spectra in the very-high-energy (VHE) range above 100 GeV have large uncertainties due to the low statistics.
Since 2018, 4 GRBs have been detected above 100 GeV thanks to the improvement of the ground-based telescopes such as MAGIC and H.E.S.S.
In this presentation I report the analysis results of VHE data and possible interpretations of GRB 190114C and GRB 201216C detected by MAGIC.
