Evidence of self-organized criticality in the prompt emission of a bright gamma-ray burst
Wen-Long Zhang, Wen-Jun Tan, Hao-Tian Lan +18
Gamma-ray bursts (GRBs) are the most energetic explosive events in the Universe, yet the physical mechanism of their prompt emission remains a mystery. Especially, it is unclear wh…
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…
GRM Scientific Pipeline
Ping Wang, Li Zhang, Jin Wang +18
The Gamma-Ray Monitor (GRM) is a key payload of the Space-based multiband astronomical Variable Objects Monitor (SVOM) mission, which is designed to detect gamma ray bursts (GRBs)…
Multi-wavelength study of EP250416a / GRB 250416C: An Optically Dark Long GRB with a Late Jet Break
Guoying Zhao, Duo-Le Cao, Rong-Feng Shen +29
We present multi-wavelength study of the /X-ray transient EP250416a (also designated GRB 250416C), triggered by the Einstein Probe (EP) Wide-field X-ray Telescope and also by SV…
Design and preliminary performance study of the broad-band spectrometer detector for POLAR-2
Jian-Chao Sun, Jiang He, Shuang-Nan Zhang +46
POLAR-2, the successor of the POLAR experiment aboard China's Tiangong-2 space lab, is set to be deployed on the China Space Station. The POLAR-2 mission aims to conducting high-pr…
Joint Observation of SGR J1935+2154 with \textit{Insight}-HXMT and KM40m during the active episode of October 2022
Wang-Chen Xue, Wen-Jun Tan, Yu-Xiang Huang +32
SGR J1935+2154 is the unique magnetar so far from which fast radio bursts have been detected. In October 2022, it resumed its burst activity, and we implemented a dedicated target-…
Spectral Evidence of Heavy Nuclei from the Neutron Star Crust in Magnetar Bursts
Sheng-Lun Xie, Yun-Wei Yu, Shao-Lin Xiong +1
The crust of a neutron star (NS) provides a unique laboratory for studying matter under extreme density and magnetic field conditions that cannot be realized in terrestrial experim…
Comprehensive Measurement of Spectral Evolution in a GRB Flare: High Time-Resolution Insights into the "Double-Tracking" Phenomenon
Zheng-Hang Yu, Wen-Jun Tan, Chen-Wei Wang +41
The spectral evolution characteristics of the prompt emission in gamma-ray bursts (GRBs) have been extensively studied, but detailed investigations of spectral evolution in a GRB f…
GECAM discovery of the second FRB-associated Magnetar X-ray Burst from SGR J1935+2154
Chen-Wei Wang, Shao-Lin Xiong, Yue Wang +47
Fast radio burst (FRB) is mysterious phenomenon with millisecond-duration radio pulses observed mostly from cosmological distance. The association between FRB 200428 and a magnetar…
Brightest GRB flare observed in GRB 221009A: bridge the last gap between flare and prompt emission in GRB
Zheng-Hang Yu, Chen-Wei Wang, Shao-Lin Xiong +46
Flares are usually observed during the afterglow phase of Gamma-Ray Bursts (GRBs) in soft X-ray, optical and radio bands, but rarely in gamma-ray band. Despite the extraordinary br…
Minutes-long soft X-ray prompt emission from a compact object merger
An Li, Chen-Wei Wang, Niccolò Passaleva +75
Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…
