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…
Luminosity function of Type II GRBs:differences from long GRBs
Yan-Kun Qu, Zhong-Xiao Man, Yu-Peng Yang +2
Gamma-ray bursts (GRBs) are generally categorized into long and short bursts based on their duration (). Recently, it has been proposed that GRBs can also be classified int…
The redshift evolution of the luminosity function of type II GRBs
Yan-Kun Qu, Zhong-Xiao Man, Yu-Peng Yang +3
As of December 2023, the Swift satellite has detected more than 1600 gamma-ray bursts (GRBs). We select 307 Type II GRBs for constructing the luminosity function (LF) based on the…
Modeling fast X-ray variability around an accreting black hole
Yejing Zhan, Bei You, Adam Ingram +2
X-ray inter-band time lags are observed during the outbursts of black hole X-ray binaries (BHXRBs). Timing analysis of fast variability in low Fourier frequency bands shows that hi…
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Ziteng Wang, Nanda Rea, Tong Bao +46
Recently, a class of long-period radio transients (LPTs) has been discovered, exhibiting emission on timescales thousands of times longer than radio pulsars. Several models had bee…
Structure Functions of Rotation Measures Revealing the Origin of Fast Radio Bursts
Rui-Nan Li, Zhen-Yin Zhao, Qin Wu +2
The structure function (SF) analysis is a powerful tool for studying plasma turbulence. Theoretically, the SF of Faraday rotation measure (RM) is expected to include a geometric co…
AT2020hur: A Possible Optical Counterpart of FRB 180916B
Long Li, Qiao-Chu Li, Shu-Qing Zhong +4
The physical origin of fast radio bursts (FRBs) remains unclear. Finding multiwavelength counterparts of FRBs can be a breakthrough in understanding their nature. In this work, we…
X-ray Plateaus in Gamma-Ray Burst Afterglows and Their Application in Cosmology
Fan Xu, Chen-Han Tang, Jin-Jun Geng +4
For gamma-ray bursts (GRBs) with a plateau phase in the X-ray afterglow, a so called correlation has been found which tightly connects the isotropic energy of the prompt GR…
Fast Radio Bursts from the Inspiral of Double Neutron Stars
Jie-Shuang Wang, Yuan-Pei Yang, Xue-Feng Wu +2
In this paper we propose that a fast radio burst (FRB) could originate from the magnetic interaction between double neutron stars (NSs) during their final inspiral within the frame…
