中文摘要
在该计划的支持下,研究了伽马射线暴的高能伽马射线和中微子发射。特别是,我可以在GEANT4工具包的帮助下评估来自伽马射线暴的TeV伽马射线的发射率,这使我能够正确地估计发射率。多亏了这个项目,我的研究是世界上最可靠的。我的研究成果现在被IceCube团队用作高能GRB中微子本底的模板,并有望在不久的将来探测到GRB中微子。
英文摘要
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.
