Ultra-high-energy -ray imprints from PeV particles accelerated by supernova remnants
Zhen Cao, F. Aharonian, Y. X. Bai +320
The quest for the origin of cosmic ray (CRs) is a fundamental issue in astrophysics. Shocks of supernova remnants (SNRs) have been considered as the dominant contributors to Galact…
Synchrotron polarization of anisotropic electron distribution in GRB prompt emission
Kang-Fa Cheng, Kai-Xian Luo, Xiao-Hong Zhao +7
In gamma-ray bursts (GRBs), the electron pitch angle () is usually assumed to be isotropically distributed. However, recent numerical simulations indicate that only the high-en…
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…
