In this paper, we perform a comprehensive analysis of the high-energy data of the recent bright short GRB 200415A, which was located close to the Sculptor galaxy. Our results suggest that a magnetar giant flare provides the most natural explanation for most observational properties of GRB 200415A, including its location, temporal and spectral features, energy, statistical correlations, and high-energy emissions. On the other hand, the compact star merger GRB model is found to have difficulty reproducing such an event in a nearby distance. Future detections and follow-up observations of similar events are essential to firmly establish the connection between SGR giant flares and a subsample of nearby short GRBs.   Rotational damping in a multi-j shell particles-rotor model 期刊论文  OAI收割 NUCLEAR PHYSICS A, 2005, 卷号: 753, 期号: 40910, 页码: 136-151 作者:  Sakata, F;  Guo, L;  Meng, H;  Zhao, EG;  Guo, L , Ibaraki Univ, Dept Math Sci, Mito, Ibaraki 3108512, Japan.   |  收藏  |  浏览/下载：23/0  |  提交时间：2012/08/30 Gamma-ray Correlations  Superdeformed Nuclei  Transition Strength  Chaotic Behavior  Level Statistics  Cranking  Motion  Dependence  States  Onset
