Identifying the poynting-flux-dominated outflow of Fermi GRBs with non-thermal spectrum and its energy-resolved light curve fitting
Xue-Zhao Chang, HouJun Lü, Zhao-Wei Du +2
The jet compositions of gamma-ray bursts (GRBs) are very important to understand the energy dissipation and radiation mechanisms, but it remains an open question in GRB physics. In…

Signature of a magnetar central engine with precession motion in the X-ray emission of GRB 220711B
Ying-Ze Shan, Xing Yang, Hou-Jun Lü +6
The -ray light curve of long-duration GRB 220711B, is characterized by a multi-peaked structure with a duration lasting 105 seconds. More interestingly, the X-ray aftergl…
