Constraining gamma-ray burst viewing angles with Swift/XRT afterglow light curves
Cheng-Jie Sun, Shuang-Xi Yi, Lin Zhou +6
Gamma-ray bursts (GRBs) are among the most energetic phenomena in the universe, and their afterglow light curves encode information about jet geometry and viewing angle. To constra…
Multi-scale Memory and Regime Shift in the Hyperactive Repeating FRB 20240114A
Wen-Long Zhang, Sheng-Lun Xie, Jun-Jie Wei +5
We present a statistical analysis of FRB~20240114A, a hyperactive repeating fast radio burst, based on 11,553 bursts detected by FAST over 214 days. Our main findings are fourfold.…
Evidence of self-organized criticality in the prompt emission of a bright gamma-ray burst
Wen-Long Zhang, Wen-Jun Tan, Hao-Tian Lan +18
Gamma-ray bursts (GRBs) are the most energetic explosive events in the Universe, yet the physical mechanism of their prompt emission remains a mystery. Especially, it is unclear wh…
Constraining Circum-burst Environments of GRBs with Jet Break Features in X-ray Afterglows
Si-Ji Xin, Yu-Qi Zhou, Sheng-Jin Sun +6
The nature of the circum-burst medium serves as a key diagnostic for probing the progenitor systems and the physics of relativistic jet propagation in gamma-ray bursts (GRBs). In t…
Magnetar-powered long gamma-ray bursts and connection to superluminous supernovae and fast radio bursts
Yu-Qi Zhou, Shuang-Xi Yi, Yu-Peng Yang +4
Based on X-ray afterglow observations from the Swift satellite, we construct a sample of 169 long gamma-ray bursts (LGRBs) exhibiting the canonical magnetar plateau signature, i.e.…
Spectral Hardness as the Primary Discriminator: Unveiling the Collapsar--Merger Boundary with a Gold-Standard Gamma-Ray Burst Sample
Xue Zhang, Yan-Kun Qu, Shuang-Xi Yi +4
In this Letter, we establish a robust, physically motivated classification method using a Support Vector Machine (SVM) trained on a "gold-standard" sample of 24 GRBs with spectrosc…
