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…
GRB 250706B/C: Insight-HXMT Discovery of a High-Luminosity Burst as a Candidate for Fallback-Regulated Accretion in the Prompt Emission
Chen-Wei Wang, R. Moradi, Shao-Lin Xiong +15
Fallback accretion in collapsar models is often associated with underluminous gamma-ray bursts (GRBs), leading to the widespread view that fallback-fed engines may be intrinsically…
A 4.5-s Quasiperiodic Spectral Oscillation in GRB 230307A: Evidence for Free Precession of a Post-Merger Magnetar?
Run-Chao Chen, Jun Yang, Bin-Bin Zhang +4
Millisecond magnetars, rapidly rotating neutron stars with ultra-strong magnetic fields, have long been proposed as central engines of gamma-ray bursts (GRBs). For GRBs produced by…
Jet-Structure Imprint on the Curvature Tail of Gamma-Ray Burst Prompt Emission
Zhen-Yu Yan, Xiao-Hong Zhao, Hendrik J. van Eerten +7
Even though the prompt emission of gamma-ray bursts (GRBs) is highly beamed, high-latitude emission still produces a distinct light curve break after the intrinsic emission ceases…
The trigger and localization system of SVOM-GRM
Jiang He, Jian-Chao Sun, Yue Huang +20
The Space multi-band Variable Object Monitor (SVOM) is an astronomical satellite jointly developed by China and France, primarily focused on the detection of gamma-ray bursts (GRBs…
The Gamma-Ray Monitor onboard the SVOM satellite
Jian-Chao Sun, Yong-Wei Dong, Jiang He +21
The Gamma-Ray Monitor (GRM) is a key scientific payload onboard the Space-based Multi-band Variable Object Monitor (SVOM) satellite, designed specifically for the detection and stu…
