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…
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…
Galactic constraints on spinning primordial black hole dark matter from interstellar dust heating
Shaobin Hu, Yupeng Yang, Chengjie Sun +5
Primordial black holes (PBHs) are compelling dark matter candidates. PBHs with masses between and can heat interstellar dust via Hawking radiation.…
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.…
Cosmological constraints on the big bang quantum cosmology model
Yicheng Wang, Yupeng Yang, Xinyi Dai +3
The big bang quantum cosmology model introduces the trace of the Schouten tensor as a form of dynamic dark energy. Together with cold dark matter, these components form the so-…
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…
Redshift evolution of the Hubble constant: Constraints and new insights from an interacting dark energy model
Xinyi Dai, Yupeng Yang, Yicheng Wang +3
We develop a modified interacting dark energy (IDE) model to study the redshift evolution of the Hubble constant (), in light of the Hubble tension. In this framework, the ene…
