Evidence for a Damped Millisecond Quasi-Periodic Structure in a Fast Radio Burst
Shuo Xiao, Zheng-Huo Jiang, Di Li
Fast radio bursts (FRBs) are millisecond-duration transients of unknown origin, likely associated with compact astrophysical objects. We report evidence for a damped millisecond qu…
Joint Observation of SGR J1935+2154 with \textit{Insight}-HXMT and KM40m during the active episode of October 2022
Wang-Chen Xue, Wen-Jun Tan, Yu-Xiang Huang +32
SGR J1935+2154 is the unique magnetar so far from which fast radio bursts have been detected. In October 2022, it resumed its burst activity, and we implemented a dedicated target-…
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…
A 50 s quasi-periodic oscillation in the early X-ray afterglow of GRB 220711B
H. Gao, W. -H. Lei, S. Xiao +19
It is generally believed that long duration gamma-ray bursts (GRBs) originate from the core collapse of rapidly spinning massive stars and at least some of them are powered by hype…
