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…
