AI 中文摘要
费米伽马射线暴监测器(GBM)已运行超过17年,期间观测到来自软伽马重复暴(SGRs,又称磁星)的一千多次爆发。磁星作为极端物理的实验室,是中子星的一个子类别,其特征是极强的磁场,通过电磁波谱上的持续辐射和短瞬变辐射组合被观测到。我们发布了GBM的SGR短暴综合星表,该星表取代了Collazzi等人2015年的5年期星表。新星表包含17年间观测到的1254次SGR短暴,提供了对磁星爆发最长的不间断、高灵敏度全天监测,具有前所未有的光谱和时间分辨率。该星表包含来自17个独特银源的爆发,其中SGR J1935+2154和SGR J1550-5418的爆发贡献最大。我们呈现了这些爆发的整体特征,如持续时间、不同光子模型的光谱参数、流量,以及与其他任务近期发布的星表和之前的GBM磁星星表的比较结果。该机器可读星表,以及爆发光谱和响应文件,已向公众开放供科学界使用。
英文摘要
The Fermi Gamma-ray Burst Monitor (GBM) has been in operation for over 17 years, during which it has observed more than a thousand bursts from soft gamma repeaters (SGRs), also known as magnetars. Serving as a laboratory for extreme physics, magnetars are a sub-family of neutron stars characterized by extreme magnetic field strength, observed through a combination of persistent and short transient emission across the electromagnetic spectrum. We present the comprehensive GBM catalog of SGR short bursts which supersedes the 5-year catalog of Collazzi et al. 2015. The new catalog contains 1254 SGR short bursts observed over 17 years, providing the longest uninterrupted, high-sensitivity all-sky monitoring of magnetar bursts with unprecedented spectral and temporal resolution. Our catalog contains bursts from 17 unique Galactic sources, with major contributions by bursts from SGR J1935+2154 and SGR J1550-5418. We present overall characteristics of these bursts, such as the durations, spectral parameters for various photon models, fluxes, as well as their comparison with recently published catalogs of other missions and the previous GBM magnetar catalog. The machine readable catalog, as well as burst spectra and response files are made publicly available for the community.
