LUNCH: A Lightweight Unified Deep-Learning Framework for General Transients Classification in High-Energy Time-Domain Astronomy
Peng Zhang, Chen-Wei Wang, Zheng-Hang Yu +19
The increasing data volume of high-energy space monitors necessitates real-time, automated transient classification for multi-messenger follow-up. Conventional methods rely on empi…
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…
BREAKFAST: A Framework for general joint BA duty and follow-up guidance of multiple -ray monitors
Chen-Wei Wang, Peng Zhang, Shao-Lin Xiong +30
With the growing number of gamma-ray monitors in operation, several research teams have adopted a strategy of joint operation and scientific duty to improve efficiency. A successfu…
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…
Extending the short gamma-ray burst population from sub-threshold triggers in Fermi/GBM and GECAM data and its implications
Ce Cai, Shao-Lin Xiong, Yan-Qiu Zhang +21
Detection of short gamma-ray bursts (SGRBs) is critically important for the research of compact object mergers and multi-messenger astrophysics, but a significant part of SGRBs fal…
Multi-Instrument Search for Gamma-Ray Counterpart of X-ray Transients detected by EP/WXT
Yan-Qiu Zhang, Wang-Chen Xue, Jin-Peng Zhang +25
As a soft X-ray imager with unprecedentedly large field of view, EP/WXT has detected many (fast) X-ray transients, whose nature is very intriguing. Whether there is gamma-ray count…
