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…
Refining primordial black hole dark matter constraints with dust heating: the role of spin and halo profile dependence
Shaobin Hu, Yupeng Yang, Chengjie Sun +5
The paper studies how spinning primordial black holes heat interstellar dust via Hawking radiation and derives constraints on their dark‑matter fraction, examining how these limits…
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…
Exploring the central engines of gamma-ray bursts from prompt light curves
Xue Zhang, Shuang-Xi Yi, Wei-Hua Lei +6
Hyperaccreting stellar-mass black hole systems are leading candidates for the central engines of gamma-ray bursts (GRBs). Their jets are thought to be powered by either the Blandfo…
The Role of Plasma Lensing in Fast Radio Bursts
R. N. Li, Y. B. Wang, S. X. Yi +2
Growing evidence indicates that some fast radio bursts (FRBs) reside in dense, magneto-ionic environments where extrinsic propagation effects can substantially reshape the observed…
