GRB light-curve decay indices with Swift

In this work, we study the distribution of temporal power-law decay indices, {alpha}, in the gamma-ray burst (GRB) afterglow phase, fitted for 176 GRBs (139 long GRBs, 12 short...本研究聚焦伽马射线暴（gamma-ray burst，以下简称GRB）余辉阶段的时间幂律衰减指数α的分布规律，针对176例GRB样本开展拟合分析，其中包含139例长GRB、12例短GRB……
