Description
In this study, we present a comprehensive catalog of short bursts from magnetars based on thirteen years of NuSTAR observations. We compiled all short bursts from observed magnetars to analyze their durations, spectral properties, and the relationships between these characteristics across different sources. In the duration distribution, we clearly observed that bursts from SGR J1935+2154 are significantly longer than those from other sources. For the spectral analysis, we employed several simple thermal and non--thermal spectral model to characterize the burst emission. A positive correlation was observed between the blackbody temperatures ($kT$) and the burst flux in the two blackbody model, suggesting a consistent property in the underlying radiative processes. This short burst catalog provides a detailed database for short bursts observed by NuSTAR. It potentially provides new directions and understanding of physical mechanisms of magnetar bursts.
