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…
Identifying Compton-thick active galactic nuclei in the COSMOS. II. Searching among mid-infrared selected AGNs
Xiaotong Guo, Qiusheng Gu, Guanwen Fang +7
Compton-thick active galactic nuclei (CT-AGNs), defined by column density , are so heavily absorbed that their X-ray e…
Multi-year Polarimetric Monitoring of Four CHIME-Discovered Repeating Fast Radio Bursts with FAST
Yi Feng, Yong-Kun Zhang, Jintao Xie +50
In this study, we report multi-year polarization measurements of four repeating FRBs initially discovered by CHIME: FRBs~20190117A, 20190208A, 20190303A, and 20190417A. We observed…
Narrowly-Banded Spectra with Peak Frequency Around 1 GHz of FRB 20201124A: Implications for Energy Function and Radiation Physics
Fen Lyu, En-Wei Liang, D. Li
The radiation physics of fast radio bursts (FRBs) remains an open question. Current observations have discovered that narrowly-banded bursts of FRB 20201124A are active in 0.4-2 GH…
A Channel to Form Fast-spinning Black Hole-Neutron Star Binary Mergers as Multimessenger Sources. II. Accretion-induced Spin-up
Zhen-Han-Tao Wang, Rui-Chong Hu, Ying Qin +7
In this work, we investigate an alternative channel for the formation of fast-spinning black hole-neutron star (BHNS) binaries, in which super-Eddington accretion is expected to oc…
Confining Burst Energy Function and Spectral Fringe Pattern of FRB 20121102A with Multifrequency Observations
Fen Lyu, Ji-Gui Cheng, En-Wei Liang +3
The observed spectral shapes variation and tentative bimodal burst energy distribution (E-distribution) of fast radio burst (FRB) 20121102A with the FAST telescope are great puzzle…
Comparison of Burst Properties between FRB 20190520B and FRB 20121102A
Fen Lyu, En-Wei Liang
A comparative analysis of the individual bursts between FRB 20190520B and FRB 20121102A is presented by compiling a sample of bursts in multiple wavelengths. It is found that the p…
Diagnosing Circumburst Environment with Multiband Gamma-Ray Burst Radio Afterglows
Bo Zhang, Liang-Duan Liu, Tian-Rui Sun +2
It has been widely recognized that gamma-ray burst (GRB) afterglows arise from interactions between GRB outflow and circumburst medium, while their evolution follows the behaviors…
A comparison between repeating bursts of FRB 121102 and giant pulses from Crab pulsar and its applications
Fen Lyu, Yan-Zhi Meng, Zhen-Fan Tang +6
There are some similarities between bursts of repeating fast radio bursts (FRBs) and giant pulses (GPs) of pulsars. To explore possible relations between them, we study the cumulat…
Self-organized Criticality in Multi-pulse Gamma-Ray Bursts
Fen Lyu, Ya-Ping Li, Shu-Jin Hou +3
The variability in multi-pulse gamma-ray bursts (GRBs) may help to reveal the mechanism of underlying processes from the central engine. To investigate whether the self-organized c…
Distributions of Gamma-Ray Bursts and Blazars in the Plane and Possible Implications for their Radiation Physics
Fen Lyu, En-Wei Liang, Yun-Feng Liang +5
We present a spectral analysis for a sample of redshift known GRBs observed with {\em Fermi}/GBM. Together with the results derived from our systematical spectral energy distributi…
