ELISA: A Bayesian X/-ray Spectral Analysis Toolkit
Wang-Chen Xue, Sheng-Lun Xie, Chao Zheng +11
Forward-folded X/-ray spectral fitting increasingly benefits from Bayesian workflows to better capture counting statistics, background uncertainties, and complex parameter degen…
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…
Tianwen-2 target asteroid (469219) Kamo'oalewa probably develops an Itokawa-compositional but ultra-highly space-weathered surface
Pengfei Zhang, Guozheng Zhang, Zichen Wei +45
China's Tianwen-2 mission plans to return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo'oalewa. Previous studies linked Kamo'oalewa to lunar compositio…
Brightest GRB flare observed in GRB 221009A: bridge the last gap between flare and prompt emission in GRB
Zheng-Hang Yu, Chen-Wei Wang, Shao-Lin Xiong +46
Flares are usually observed during the afterglow phase of Gamma-Ray Bursts (GRBs) in soft X-ray, optical and radio bands, but rarely in gamma-ray band. Despite the extraordinary br…
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…
Advancing Identification method of Gamma-Ray Bursts with Data and Feature Enhancement
Peng Zhang, Bing Li, Ren-Zhou Gui +12
Gamma-ray bursts (GRBs) are challenging to identify due to their transient nature, complex temporal profiles, and limited observational datasets. We address this with a one-dimensi…
