Identifying Merger-Driven and Collapsar-Driven Gamma-Ray Bursts with Precursor based Solely on Prompt Emission
Si-Yuan Zhu, Pak-Hin Thomas Tam, Fu-Wen Zhang +2
Gamma-ray bursts (GRBs) are generally classified as Type~I GRBs, which originate from compact binary mergers, and Type~II GRBs, which originate from massive collapsars. The traditi…

A Study of the Spectral properties of Gamma-Ray Bursts with the Precursors and Main bursts
Hui-Ying Deng, Zhao-Yang Peng, Jia-Ming Chen +2
There is no consensus yet on whether the precursor and the main burst of gamma-ray bursts (GRBs) have the same origin, and their jet composition is still unclear. In order to furth…
