Propagation of a Short GRB Jet in the Ejecta: Jet Launching Delay Time, Jet Structure, and GW170817/GRB 170817A
Jin-Jun Geng, Bing Zhang, Anders Kölligan +2
We perform a series of relativistic magnetohydrodynamics simulations to investigate how a hot magnetic jet propagates within the dynamical ejecta of a binary neutron star merger, w…
Statistical Study of Gamma-Ray Bursts with a Plateau Phase in the X-ray Afterglow
Chen-Han Tang, Yong-Feng Huang, Jin-Jun Geng +1
A plateau phase in the X-ray afterglow is observed in a significant fraction of gamma-ray bursts (GRBs). Previously, it has been found that there exists a correlation among three k…
Statistical properties of the repeating fast radio burst source FRB 121102
Bing Li, Long-Biao Li, Zhi-Bin Zhang +4
Currently, FRB 121102 is the only fast radio burst source that was observed to give out bursts repeatedly. It shows a high repeating rate, with more than one hundred bursts being s…
Late-Time Afterglow from Double-Sided Structured Jets: Application to GRB 170817A
Long-Biao Li, Jin-Jun Geng, Yong-Feng Huang +1
The broadband afterglow of GW170817/GRB 170817A is believed to be from an off-axis structured jet. The central engine of a gamma-ray burst usually launches a pair of outflows that…
Inverse Compton Scattering Spectra of Gamma-Ray Burst Prompt Emission
Yue Zhang, Jin-Jun Geng, Yong-Feng Huang
Although the physical origin of gamma-ray burst (GRB) prompt emission is still controversial, synchrotron radiation from accelerated electrons is a promising mechanism. It is belie…
"Double-tracking" Characteristic of the Spectral Evolution of GRB 131231A: Synchrotron Origin?
Liang Li, Jin-Jun Geng, Yan-Zhi Meng +6
The characteristics of the spectral evolution of the prompt emission of gamma-ray bursts (GRBs), which are closely related to the radiation mechanism (synchrotron or photosphere),…
