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…
