Synchrotron Circular Polarization in Gamma-Ray Burst Prompt Optical Emission: Relativistic Thermal Electron Contribution
Kangfa Cheng, Jirong Mao, Xiaohong Zhao +4
Synchrotron circular polarization of a non-thermal power-law electron distribution in gamma-ray bursts (GRBs) has been studied. However, some numerical simulations have shown that…
Synchrotron polarization of a hybrid distribution of relativistic thermal and nonthermal electrons in GRB prompt emission
Kangfa Cheng, Jirong Mao, Xiaohong Zhao +4
Synchrotron polarization of relativistic nonthermal electrons in gamma-ray bursts (GRBs) has been widely studied. However, recent numerical simulations of relativistic shocks and m…
The polarization-angle flip in GRB prompt emission
Kangfa Cheng, Xiaohong Zhao, Jirong Mao +1
Aims. We aim to provide an explanation for the PA rotation in GRBs and find the physical conditions that lead to the rotation by 90 degrees in the toroidal magnetic-field (MF) mode…
Roles of the kinetic and dynamic mechanisms in the relation
Yi-Ping Qin, Zhi-Fu Chen
The relation is a well-known relation in gamma-ray bursts. Its implication remains unclear. We propose to investigate the underlying mechanisms of this relation by cons…
Statistical classification of gamma-ray bursts based on the Amati relation
Yi-Ping Qin, Zhi-Fu Chen
Gamma-ray bursts (GRBs) are believed to belong to two classes and they are conventionally divided according to their durations. This classification scheme is not satisfied due to t…
