A comprehensive analysis of Fermi Gamma-Ray Burst Data: IV. Spectral lag and Its Relation to Ep Evolution
Rui-Jing Lu, Yun-Feng Liang, Da-Bin Lin +6
The spectral evolution and spectral lag behavior of 92 bright pulses from 84 gamma-ray bursts (GRBs) observed by the Fermi GBM telescope are studied. These pulses can be classified…
The three-parameter correlations about optical plateaus of gamma-ray bursts
Shu-Kun Si, Yan-Qing Qi, Feng-Xia Xue +7
Well-sampled optical light curves of 50 gamma-ray bursts (GRBs) with plateau features are compiled from the literature. By empirical fitting, we obtained the parameters of the opti…
Gamma-ray burst jet breaks revisited
Xiang-Gao Wang, Bing Zhang, En-Wei Liang +3
Gamma-ray Burst (GRB) collimation has been inferred with the observations of achromatic steepening in GRB light curves, known as jet breaks. Identifying a jet break from a GRB afte…
GRB120729A: external shock origin for both the prompt gamma-ray emission and afterglow
Li-Ye Huang, Xiang-Gao Wang, WeiKang Zheng +7
Gamma-ray burst (GRB) 120729A was detected by Swift/BAT and Fermi/GBM, and then rapidly observed by Swift/XRT, Swift/UVOT, and ground-based telescopes. It had a single long and smo…
First Electromagnetic Pulse Associated with a Gravitational-Wave Event: Profile, Duration, and Delay
Da-Bin Lin, Tong Liu, Jie Lin +3
We study the first electromagnetic pulse after the gravitational wave chirp signal, focusing on the profile and duration. It is found that the light curve, especially the steep dec…
