Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary

G. L. Huang, Q. C. Zhao, L. Tao +30

We report the discovery of a new X-ray transient, EP J175257.3-351923 (EP250916a), by the Einstein Probe (EP) near the Galactic plane. The outburst lasted for at least 250\,days, r…

An energetic dirty fireball detected in soft X-rays

C. -Y. Dai, J. Quirola-Vásquez, Y. -H. Wang +76

The collapse of massive stars drives explosions that power relativistic fireballs. If only a small amount of matter is entrained, such clean fireballs can expand with Lorentz facto…

Multi-wavelength Study of A Superflare on RS CVn-type Star HD22468 Triggered at Hard X-ray by SVOM

J. Wang, W. J. Xie, F. Cangemi +36

Detection of stellar flares at hard X-ray is still rare at the current stage. A transient was recently detected by the hard X-ray camera, ECLAIRs onboard the SVOM mission at 11:39:…

JWST reveals a supernova following a gamma-ray burst at z 7.3

A. J. Levan, B. Schneider, E. Le Floc'h +50

The majority of energetic long-duration gamma-ray bursts (GRBs) are thought to arise from the collapse of massive stars, making them powerful tracers of star formation across cosmi…

Picking-up Local GRB Candidates Based on Their Host Galaxies

J. Wang, Y. Xu, L. J. Chen +4

Rapid identification of candidates of high-value gamma-ray bursts (GRBs), including both high- and local events, is crucial for outlining subsequent observational strategy. In t…

Enhancing Fault Diagnosis in GWAC: A Monitoring System for Telescope Arrays

Y. Xu, G. W. Li, J. Wang +6

The Ground-based Wide-Angle Cameras array (GWAC) necessitates the integration of over 100 hardware devices, more than 100 servers, and upwards of 2500 software modules, all synchro…
