A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However,…

Searching for Gamma Ray Bursts associated with CHIME Fast Radio bursts
Yi-Fang Liang, Ye Li, Bao Wang +3
Fast radio bursts (FRBs) and gamma-ray bursts (GRBs) are both linked to compact-object activity, yet their possible connection remains unclear. Here we perform a systematic search…

Spreading and multi-wavelength emissions of an ultra-narrow relativistic jet from GRB 221009A
Jin-Jun Geng, Ying-Kang Zhang, Hao-Xuan Gao +19
The long-term evolution of relativistic jets in gamma-ray bursts (GRBs), particularly from days to months post-burst, remains a fundamental puzzle in astrophysics. Here, we report…
