A comparison between repeating bursts of FRB 121102 and giant pulses from Crab pulsar and its applications
Fen Lyu, Yan-Zhi Meng, Zhen-Fan Tang +6
There are some similarities between bursts of repeating fast radio bursts (FRBs) and giant pulses (GPs) of pulsars. To explore possible relations between them, we study the cumulat…
The time-resolved spectra of photospheric emission from a structured jet for gamma-ray bursts
Yan-Zhi Meng, Liang-Duan Liu, Jun-Jie Wei +2
The quasi-thermal components found in many Fermi gamma-ray bursts (GRBs) imply that the photosphere emission indeed contributes to the prompt emission of many GRBs. But whether the…
"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),…
Multi-color blackbody emission in GRB 081221
Shu-Jin Hou, Bin-Bin Zhang, Yan-Zhi Meng +9
The radiation mechanism of the prompt emission of gamma-ray bursts (GRBs) remains an open question. Although their spectra are usually well fitted with the empirical Band function,…
Brightening X-ray/Optical/Radio Emission of GW170817/SGRB 170817A: Results of an Electron-Positron Wind from the Central Engine?
Jin-Jun Geng, Zi-Gao Dai, Yong-Feng Huang +4
Recent follow-up observations of the binary neutron star (NS) merging event GW170817/SGRB 170817A reveal that its X-ray/optical/radio emissions are brightening continuously up to $…
