Spectral properties of magnetar bursts

We present our broadband (2-250keV) time-averaged spectral analysis of 388 bursts from SGR J1550-5418, SGR 1900+14, and SGR 1806-20 detected with the Rossi X-ray Timing Explorer...本工作针对通过罗西X射线计时探测器（Rossi X-ray Timing Explorer）探测到的SGR J1550-5418、SGR 1900+14与SGR 1806-20的388次暴，开展了2-250keV宽能段的时间平均谱分析。
