Neutrino constraints and detection prospects from gamma-ray bursts with different jet compositions
Yang-Dong-Jun Ou, Hou-Jun Lü, Xue-Zhao Chang +2
The prompt emission mechanism of gamma-ray bursts (GRBs) is a long-standing open question, and GRBs have been considered as potential sources of high-energy neutrinos. Despite many…

The thermal emission in short GRBs with extended emission observed by Fermi/GBM
Xue-Zhao Chang, Hou-Jun Lü, Xing Yang +2
Short gamma-ray bursts (SGRBs) with extended emission (EE) are composed of initial main emission (ME) with a short-hard spike, followed by a long-lasting EE. Whether the ME and EE…
