The Evolution of Thermal and Non-thermal Emission Components in GRB 250920C
Jia-Ming Chen, Ke-Rui Zhu, Shan Chang +5
We present a temporal and time-resolved spectral analysis of GRB 250920C using \textit{Fermi}/GBM and \textit{Swift}/BAT data. The prompt emission consists of two distinct episodes…
Modeling Gamma-Ray Burst Spectra with Convolutional Neural Networks: Fast-Cooling Synchrotron Emission in a Decaying Magnetic Field
Jia-Ming Chen, Ke-Rui Zhu, Shan Chang +3
The radiation mechanism of gamma-ray burst (GRB) prompt emission remains uncertain. Although the fast-cooling synchrotron model in a decaying magnetic field can account for the cha…
Fast-Cooling Synchrotron in Decaying Magnetic Fields: Implications for the GRB Spectral Distribution
Jia-Ming Chen, Ke-Rui Zhu, Zhao-Yang Peng +5
The prompt-emission spectra of gamma-ray bursts (GRBs) are commonly described by the empirical Band function. The typical low-energy spectral index is , which poses a chal…
Evidence for the transition from thermal to non-thermal emission in the prompt emission of GRB 161117A
Xue-Zhao Chang, HouJun Lü, Jia-Ming Chen +1
GRB 161117A is a long-duration GRB with three main overlapping peaks. By analyzing the time-resolved spectra of its data observed with the Gamma-Ray Burst Monitor (GBM) on board th…
Constraint on the Physical Origin of Gamma-Ray Burst Prompt Emission via Its Nondetected Diffuse Neutrino Emission
Yang-Dong-Jun Ou, Hou-Jun Lü, Jia-Ming Chen +2
The physical origin of prompt emission in gamma-ray bursts (GRBs) remains an open question since it has been studied more than half a century. Three alternative models (i.e. dissip…
A re-identification of six Candidate Gravitationally Lensed Gamma-Ray Bursts
Yu Zhao, Zhao-Yang Peng, Jia-Ming Chen +2
The gravitational lensing effect of gamma-ray bursts (GRBs) holds significant and diverse applications in the field of astronomy. Nevertheless, the identification of millilensing e…
A Study of the Spectral Properties of Gamma-Ray Bursts with the Main and Second Bursts
Ze-Lian Du, Zhao-Yang Peng, Jia-Ming Chen +2
The origins of the main burst and second burst of gamma-ray bursts (GRBs) and the composition of their jets remain uncertain. To explore this complex subject more thoroughly, we co…
Classification and physical characteristics analysis of Fermi-GBM Gamma-ray bursts based on Deep-learning
Jia-Ming Chen, Ke-Rui Zhu, Zhao-Yang Peng +1
The classification of Gamma-Ray Bursts has long been an unresolved problem. Early long and short burst classification based on duration is not convincing due to the significant ove…
The thermal emission in short GRBs with extended emission observed by Fermi/GBM
Xue-Zhao Chang, Hou-Jun Lü, Xing Yang +2
Short gamma-ray bursts (SGRBs) with extended emission (EE) are composed of initial main emission (ME) with a short-hard spike, followed by a long-lasting EE. Whether the ME and EE…
A Study of the Spectral properties of Gamma-Ray Bursts with the Precursors and Main bursts
Hui-Ying Deng, Zhao-Yang Peng, Jia-Ming Chen +2
There is no consensus yet on whether the precursor and the main burst of gamma-ray bursts (GRBs) have the same origin, and their jet composition is still unclear. In order to furth…
A comparative analysis of two peculiar long Gamma-ray bursts: GRB 230307A and GRB 211211A
Zhao-Yang Peng, Jia-Ming Chen, Jirong Mao
GRB 211211A is a peculiar long Gamma-ray burst (GRB) with very high brightness and short burst properties. It's full lightcurve consists of three emission episodes, i.e. a precurso…
Thermal and nonthermal emission from a peculiar long-duration GRB 211211A
Xue-Zhao Chang, Hou-Jun Lü, Xing Yang +2
Long-duration GRB 211211A that lacks a supernova emission even down to very stringent limits at such a low redshift and is associated with kilonova emission, suggests tha…
