Flux and Spectral Variation Characteristics of 3C 454.3 at the GeV Band
Hai-Ming Zhang, Jin Zhang, Rui-Jing Lu +3
We analyze the long-term lightcurve of 3C 454.3 observed with Fermi/LAT and investigate its relation to the flux in the radio, optical, and X-ray bands. By fitting the 1-day binned…
External Shock in a Multi-Bursting Gamma-ray Burst: Energy Injection Phase induced by the Later Launched Ejecta
Da-Bin Lin, Bao-Quan Huang, Tong Liu +3
Central engine of gamma-ray bursts (GRBs) may be intermittent and launch several episodes of ejecta separated by a long quiescent interval. In this scenario, an external shock is f…
Constraining the Type of Central Engine of GRBs with Swift Data
Liang Li, Xue-Feng Wu, Wei-Hua Lei +3
The central engine of gamma-ray bursts (GRBs) is poorly constrained. There exist two main candidates: a fast-rotating black hole and a rapidly spinning magnetar. Furthermore, the X…
{\em Fermi}/GBM Short Gamma-ray Burst Catalog and Case Study for GRB 170817A/GW 170817
Rui-Jing Lu, Shen-Shi Du, Ji-Gui Cheng +4
Motivating by the discovery of association between GW 170817 and sGRB 170817A, we present a comprehensive analysis for sGRBs observed with Fermi/GBM in 9 operation years and study…
Signature of a New-Born Black Hole from the Collapse of a Supra-massive Millisecond Magnetar
Wei Chen, Wei Xie, Wei-Hua Lei +5
The X-ray plateau followed by a steep decay ("internal plateau") has been observed in both long and short gamma-ray burst (GRBs), implying a millisecond magnetar operating in some…
Steep Decay Phase Shaped by the Curvature Effect. II. Spectral Evolution
Da-Bin Lin, Hui-Jun Mu, Yun-Feng Liang +5
We derive a simple analytical formula to describe the evolution of spectral index in the steep decay phase shaped by the curvature effect with assumption that the spectral para…
