| Research Abstract |
Emission of High-Energy Gamma-rays and Neutrinos from Gamma-Ray Bursts are investigated with the support of this program. Especially, I could evaluate the emissivity of TeV gamma-rays from Gamma-Ray Bursts with a help of the toolkit GEANT4, which enables me to estimate the emissivity correctly. Thanks to this program, my study has been the most reliable one in the world. The result of my research is now used as an template of high-energy GRB neutrino background by IceCube team, and the GRB neutrinos are being expected to be detected in the near future.
