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…
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-…
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…
Eclipsed X-ray Bursts from Magnetar SGR J1935+2154 and the Fireball Measurements
Sheng-Lun Xie, Aming Chen, Yun-Wei Yu +17
In theory, burst activity of the magnetar can lead to the formation of fireballs trapped by the magnetic field and corotating with the star. However, the smoking-gun observational…
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…
Systematic Study of the Simultaneous Events Detected by GECAM
Yang-Zhao Ren, Feng-Rong Zhu, Shao-Lin Xiong +45
GECAM is a constellation of all-sky monitors in hard X-ray and gamma-ray band primarily aimed at high energy transients such as gamma-ray bursts, soft gamma-ray repeaters, solar fl…
