GECAM discovery of a peculiar magnetar X-ray burst (MXB 221120) from SGR J1935+2154 associated with a fast radio burst
Wen-Jun Tan, Yue Wang, Chen-Wei Wang +50
Fast radio bursts (FRBs) are enigmatic cosmic transients of millisecond duration observed in the radio band. The identification of FRB-associated magnetar X-ray bursts (MXBs) from…
Finding the Particularity of the Active Episode of SGR J1935+2154 during Which FRB 20200428 Occurred: Implication from Statistics of Fermi/GBM X-Ray Bursts
Sheng-Lun Xie, Yun-Wei Yu, Shao-Lin Xiong +5
By using the Fermi/Gamma-ray Burst Monitor data of the X-ray bursts (XRBs) of SGR J1935+2154, we investigate the temporal clustering of the bursts and the cumulative distribution o…
GECAM Observations of the Galactic Magnetar SGR J1935+2154 during the 2021 and 2022 Burst Active Episodes. I. Burst Catalog
Sheng-Lun Xie, Ce Cai, Yun-Wei Yu +34
Magnetar is a neutron star with an ultrahigh magnetic field ( G). The magnetar SGR J1935+2154 is not only one of the most active magnetars detected so far, bu…
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…
GECAM Discovery of Peculiar Oscillating Particle Precipitation Events
Chenwei Wang, Shaolin Xiong, Yi Zhao +52
Charged particle precipitation typically manifests as a gradual increase and decrease of flux observed by space detectors. Cases with rapidly flux variation are very rare. Periodic…
Pitch Angle Measurement Method based on Detector Counts Distribution. -I. Basic conception
Chenwei Wang, Shaolin Xiong, Hongbo Xue +36
As an X-ray and gamma-ray all-sky monitor aiming for high energy astrophysical transients, Gravitational-wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) has al…
