With the growing number of gamma-ray monitors in operation, several research teams have adopted a strategy of joint operation and scientific duty to improve efficiency. A successfu…
Unveil A Peculiar Light Curve Pattern of Magnetar Burst with GECAM observations of SGR J1935+2154
Yue Wang, Chen-Wei Wang, Shaolin Xiong +28
Magnetar X-ray Burst (MXB) is usually composed of a single pulse or multiple pulses with rapid rise and brief duration mostly observed in hard X-ray (soft gamma-ray) band. Previous…
Eclipsed X-ray Bursts from Magnetar SGR J1935+2154 and the Fireball Measurements
Sheng-Lun Xie, Aming Chen, Yun-Wei Yu +17
In theory, burst activity of the magnetar can lead to the formation of fireballs trapped by the magnetic field and corotating with the star. However, the smoking-gun observational…
The Origin of Cross-Energy-Similar FRED Profiles in Gamma-Ray Bursts Pulses
Shu-Xu Yi, Chen-Wei Wang, Shao-Lin Xiong +5
To understand the physical mechanisms underlying the prompt emission of gamma-ray bursts (GRB), single FRED (Fast-Rise-Exponential-Decay) profile GRBs serve as an ideal sample, as…
Evidence for a brief appearance of gamma-ray periodicity after a compact star merger
Run-Chao Chen, Bin-Bin Zhang, Chen-Wei Wang +6
The product of a compact star merger is usually hypothesized to be a hyperaccreting black hole, typically resulting in a gamma-ray burst (GRB) with a duration shorter than 2~s. How…
Extending the short gamma-ray burst population from sub-threshold triggers in Fermi/GBM and GECAM data and its implications
Ce Cai, Shao-Lin Xiong, Yan-Qiu Zhang +21
Detection of short gamma-ray bursts (SGRBs) is critically important for the research of compact object mergers and multi-messenger astrophysics, but a significant part of SGRBs fal…
