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…

Revisit the periodicity of SGR J1935+2154 bursts with updated sample

Sheng-Lun Xie, Ce Cai, Shao-Lin Xiong +30

Since FRB 200428 has been found to be associated with an X-ray burst from the Galactic magnetar SGR J1935+2154, it is interesting to explore whether the magnetar bursts also follow…

Evidence of mini-jet emission in a large emission zone from a magnetically-dominated gamma-ray burst jet

S. -X. Yi, C. -W. Wang, X. -Y. Shao +42

The second brightest GRB in history, GRB230307A, provides an ideal laboratory to study the mechanism of GRB prompt emission thanks to its extraordinarily high photon statistics and…

New insight into the Rapid Burster by Insight-HXMT

Y. P. Chen, S. Zhang, S. N. Zhang +91

We report the timing and spectral analyses upon of the type II X-ray bursts from the Rapid Burster (MXB 1730--335) observed by Insight-HXMT and Swift/XRT. By stacking the long-dura…

Magnetar emergence in a peculiar gamma-ray burst from a compact star merger

H. Sun, C. -W. Wang, J. Yang +42

The central engine that powers gamma-ray bursts (GRBs), the most powerful explosions in the universe, is still not identified. Besides hyper-accreting black holes, rapidly spinning…
