Revisiting the Multiwavelength Data of GRB 240825A: Implications for a Two-Stage Central Engine and a Dusty Environment
Ren-Jie Xiong, Zi-Qi Wang, Xiao-Li Huang +1
Reanalyzing the multi-wavelength data of GRB 240825A, we identify two distinct prompt-emission episodes, i.e. an early, spectrally soft plateau and a subsequent bright, spectrally…
Fast Optical Variability of the TeV Blazar PKS 1725+123 Observed by SVOM-VT and Insights from Multi-wavelength Follow-up Observations
Shuo-Yu Liu, Yu-Wei Yu, Ji-Shun Lian +29
PKS 1725+123 is a flat-spectrum radio quasar (FSRQ) with a redshift of . The detection of this object in the TeV band was reported by the MAGIC telescopes and H.E.S.S. in…
Do Prompt Gamma-ray Burst Fireball Composition Impact on Afterglow Emission? Cases Study for Long GRBs 080916C/090902B and Short GRBs 090510/130603B
Yu Gan, Ren-Jie Xiong, Zi-Qi Wang +3
Broadband observations with the {\em Fermi} mission reveal that a large fraction of gamma-ray burst (GRB) spectra are dominated by non-thermal emission, while a small fraction are…
GRB 250424A: A Case Study of Energy Injection with Multiwavelength Observations
Yifang Liang, Yun Wang, WeiKang Zheng +61
We present a comprehensive multiwavelength analysis of the long-duration gamma-ray burst (GRB) 250424A. Our dataset spans from the prompt gamma-ray emission to late-time optical mo…
Shear Particle Acceleration in Structured Gamma-Ray Burst Jets: IV. Thermal {\em vs.} Non-thermal Emission of the Jet Cocoon
Zi-Qi Wang, Xiao-Li Huang, Hai-Ming Zhang +1
A distinct thermal or quasi-thermal spectral component is occasionally observed in gamma-ray burst (GRB) prompt emission spectra. Taking GRB 090902B as a case study, we investigate…
Shear Particle Acceleration in Structured Gamma-Ray Burst Jets: III. The Radiation Physics of Bright Prompt Optical Flash
Zi-Qi Wang, Xiao-Li Huang, En-Wei Liang
The radiation physics of bright prompt optical emission of gamma-ray bursts (GRBs) remains a puzzle. Assuming that the GRB ejecta is structured, we investigated this issue by chara…
Shear Particle Acceleration in Structured Gamma-Ray Burst Jets: II. Viewing Angle Effect on the Prompt Emission and Application to GRB 170817A
Zi-Qi Wang, Xiao-Li Huang, En-Wei Liang
Multi-messenger observations suggest that the gamma-ray burst on Aug. 17, 2017 (GRB 170817A) resulted from off-axial observations of its structured jet, which consists of a narrow…
A two-hump spectrum in the prompt emission of GRB 240825A
Hai-Ming Zhang, Zi-Qi Wang, Cui-Yuan Dai +4
An extra hard spectral component that extends to GeV energies, in additional to the typical sub- MeV Band component, appears in several gamma-ray burst (GRBs) detected by Fermi Lar…
Shear Particle Acceleration in Structured Gamma-Ray Burst Jets: I. Physical Origin of the Band Function and Application to GRBs 090926A, 131108A, and 160509A
Zi-Qi Wang, Xiao-Li Huang, En-Wei Liang
The radiation physics of gamma-ray bursts (GRBs) remains an open question. Based on the simulation analysis and recent observations, it was proposed that GRB jets are composed of a…
