标题： A detailed radio study of the energetic, nearby and puzzling GRB 171010A

摘要： 我们报告了一项关于伽马射线暴（GRB）171010A的密集多时段射电频率观测活动的结果，该活动使用了卡尔·詹斯基甚大阵列和弧分微开尔文成像大面积阵列。我们在其首次探测后一天开始观测GRB 171010A，并能够监测接下来几周内该源的时间和光谱演化。我们将这些光谱及其演化与广义伽马射线暴余辉的标准理论进行了比较，发现总体上一致。然而，存在一些用简单的前向冲击模型难以解释的特征，我们讨论了这些差异可能的原因。这包括考虑反向冲击成分的存在、潜在的微观物理参数演化以及闪烁效应的影响。 显示英文摘要

摘要： We present the results of an intensive multi-epoch radio frequency campaign on the energetic and nearby GRB 171010A with the Karl G. Janksy Very Large Array and Arcminute Microkelvin Imager Large Array. We began observing GRB 171010A a day after its initial detection, and were able to monitor the temporal and spectral evolution of the source over the following weeks. The spectra and their evolution are compared to the canonical theories for broadband GRB afterglows, with which we find a general agreement. There are, however, a number of features that are challenging to explain with a simple forward shock model, and we discuss possible reasons for these discrepancies. This includes the consideration of the existence of a reverse shock component, potential microphysical parameter evolution and the effect of scintillation.
