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…
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…
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…
Confirmed width-Eiso and width-Liso relations in GRB: comparison with the Amati and Yonetoku relations
Zhao-Yang Peng, Yue Yin, Ting Li +2
In this paper, we select a sample including 141 BEST time-integrated F spectra and 145 BEST peak flux P spectra observed by the Konus-Wind with known redshift to recheck the connec…
Spectral lag of gamma-ray burst caused by the intrinsic spectral evolution and the curvature effect
Z. Y. Peng, Y. Yin, X. W. Bi +2
Assuming an intrinsic `Band' shape spectrum and an intrinsic energy-independent emission profile we have investigated the connection between the evolution of the rest-frame spectra…
