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…
The X-ray re-brightening of GRB afterglow revisited: a possible signature from activity of the central engine
Zhe Yang, Hou-Jun Lü, Xing Yang +2
Long-duration gamma-ray bursts (GRBs) are thought to be from core collapse of massive stars, and a rapidly spinning magnetar or black hole may be formed as the central engine. The…
Can fallback accretion on magnetar model power the X-ray flares simultaneously observed with gamma-rays of Gamma-ray bursts?
Wen-Yuan Yu, Hou-Jun Lü, Xing Yang +2
The prompt emission, X-ray plateau, and X-ray flares of Gamma-ray bursts (GRB) are thought to be from internal dissipation, and the magnetar as the central engine with propeller fa…
The Jet Composition of GRB 230307A: Poynting-Flux-Dominated Outflow?
Zhao-Wei Du, HouJun Lü, Xiaoxuan Liu +1
The jet composition of GRB plays an important role in understanding the energy dissipation and radiation mechanisms in GRB physics, but it is poorly constrained from the observatio…
