Exploring the central engines of gamma-ray bursts from prompt light curves
Xue Zhang, Shuang-Xi Yi, Wei-Hua Lei +6
Hyperaccreting stellar-mass black hole systems are leading candidates for the central engines of gamma-ray bursts (GRBs). Their jets are thought to be powered by either the Blandfo…

Constraining the initial Lorentz factor of gamma-ray bursts under different circumburst mediums
Sheng-Jin Sun, Shuang-Xi Yi, Yuan-Chuan Zou +4
The initial Lorentz factor () plays a crucial role in uncovering the physical characteristics of gamma-ray bursts (GRBs). Previous studies have indicated that the am…
