Magnetized Reverse Shock: Density-fluctuation-induced Field Distortion, Polarization Degree Reduction, and Application to GRBs
Wei Deng, Bing Zhang, Hui Li +1
The early optical afterglow emission of several gamma-ray bursts (GRBs) shows a high linear polarization degree (PD) of tens of percent, suggesting an ordered magnetic field in the…
Collision-induced magnetic reconnection and a unified interpretation of polarization properties of GRBs and blazars
Wei Deng, Haocheng Zhang, Bing Zhang +1
The jet composition and energy dissipation mechanism of Gamma-ray bursts (GRBs) and Blazars are fundamental questions which remain not fully understood. One plausible model is to i…
Polarization Signatures of Relativistic Magnetohydrodynamic Shocks in the Blazar Emission Region - I. Force-free Helical Magnetic Fields
Haocheng Zhang, Wei Deng, Hui Li +1
The optical radiation and polarization signatures in blazars are known to be highly variable during flaring activities. It is frequently argued that shocks are the main driver of t…
Efficient Production of High-energy Nonthermal Particles during Magnetic Reconnection in a Magnetically-dominated Ion-Electron Plasma
Fan Guo, Xiaocan Li, Hui Li +6
Magnetic reconnection is a leading mechanism for dissipating magnetic energy and accelerating nonthermal particles in Poynting-flux dominated flows. In this letter, we investigate…
Relativistic MHD simulations of collision-induced magnetic dissipation in Poynting-flux-dominated jets/outflows
Wei Deng, Hui Li, Bing Zhang +1
We perform 3D relativistic ideal MHD simulations to study the collisions between high- (Poynting-flux-dominated) blobs which contain both poloidal and toroidal magnetic field co…
Low Energy Spectral Index and evolution of Quasi-thermal Photosphere Emission of Gamma-Ray Bursts
Wei Deng, Bing Zhang
Recent observations by the Fermi satellite suggest that a photosphere emission component is contributing to the observed spectrum of many GRBs. One important question is whether th…
Cosmological implications of Fast Radio Burst / Gamma-Ray Burst Associations
Wei Deng, Bing Zhang
If a small fraction of Fast Radio Bursts (FRBs) are associated with Gamma-Ray Bursts (GRBs), as recently suggested by Zhang, the combination of redshift measurements of GRBs and di…
