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.   Performance of a wide field-of-view atmospheric cherenkov telescope prototype based on a refractive lens 期刊论文  iSwitch采集 Nuclear instruments & methods in physics research section a-accelerators spectrometers detectors and associated equipment, 2019, 卷号: 927, 页码: 46-53 作者:  Chen, Tianlu;  Liu, Cheng;  Gao, Qi;  Cai, Hui;  Wang, Zhen 收藏  |  浏览/下载：142/0  |  提交时间：2019/04/22 Atmospheric cherenkov telescope  Refractive lens  Wide field-of-view (fov)  Gamma-ray bursts (grbs)  Cosmic rays (crs)   Performance of a wide field-of-view atmospheric cherenkov telescope prototype based on a refractive lens 期刊论文  iSwitch采集 Nuclear instruments & methods in physics research section a-accelerators spectrometers detectors and associated equipment, 2019, 卷号: 927, 页码: 46-53 作者:  Chen, Tianlu;  Liu, Cheng;  Gao, Qi;  Cai, Hui;  Wang, Zhen 收藏  |  浏览/下载：142/0  |  提交时间：2019/04/22 Atmospheric cherenkov telescope  Refractive lens  Wide field-of-view (fov)  Gamma-ray bursts (grbs)  Cosmic rays (crs)   High-energy gamma-ray emission from gamma-ray bursts - before GLAST 期刊论文  OAI收割 FRONTIERS OF PHYSICS IN CHINA, 2008, 卷号: 3, 期号: 3, 页码: 306-330 作者:  Fan, Yi-Zhong;  Piran, Tsvi 收藏  |  浏览/下载：24/0  |  提交时间：2011/12/30 gamma-ray bursts (GRBs)  afterglows  shock waves  relativity  radiation mechanisms: nonthermal   Study on the optimum angular radius of windows in searching for TeV GRBs 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2004, 卷号: 28, 期号: 10, 页码: 1094-1098 作者:  Chen X(陈欣);  Zhou XX(周勋秀);  Hu HB(胡红波);  Liu K(刘琨);  Yang QY(杨群羽) 收藏  |  浏览/下载：8/0  |  提交时间：2016/06/29 gamma ray bursts(GRBs)  angular radius  Monte Carlo method  significance  angular resolution
