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…
Unveil A Peculiar Light Curve Pattern of Magnetar Burst with GECAM observations of SGR J1935+2154
Yue Wang, Chen-Wei Wang, Shaolin Xiong +28
Magnetar X-ray Burst (MXB) is usually composed of a single pulse or multiple pulses with rapid rise and brief duration mostly observed in hard X-ray (soft gamma-ray) band. Previous…
Resonance Capture and Stability Analysis for Planet Pairs under Type I Disk Migration
Linghong Lin, Beibei Liu, Zekai Zheng
We present a theoretical framework for investigating a two-planet system undergoing convergent type I migration in a protoplanetary disk. Our study identifies the conditions for re…
The timing and spectral properties of the 2022 outburst of SGR J1935+2154 observed with NICER
Fu Yu-Cong, Lin Lin, Ge Ming-Yu +5
The magnetar SGR J1935+2154 entered a new active episode on October 10, 2022, with X-ray bursts and enhanced persistent emission. At the tail of high burst rate interval, lasting s…
