Gamma-ray bursts (GRBs) are extremely energetic events at cosmological distances. They provide unique laboratory to investigate fundamental physical processes under extreme conditions. Due to extreme luminosities, GRBs are detectable at very high redshifts and potential tracers of cosmic star formation rate at early epoch. While the launch of Swift and Fermi has increased our understanding of GRBs tremendously, many new questions have opened up. Radio observations of GRBs uniquely probe the energetics and environments of the explosion. However, currently only 30% of the bursts are detected in radio bands. Radio observations with upcoming sensitive telescopes will potentially increase the sample size significantly and allow one to follow the individual bursts for a much longer duration and be able to answer some of the important issues related to true calorimetry, reverse shock emission, and environments around the massive stars exploding as GRBs in the early Universe.

伽玛射线暴：无线电视角

伽马射线爆发（GRB）是在宇宙学距离上极为活跃的事件。他们提供了独特的实验室来研究极端条件下的基本物理过程。由于极高的发光度，可以在非常高的红移和早期的宇宙恒星形成速率的潜在示踪剂中检测到GRB。而斯威夫特和费米的推出极大地增加了我们对GRB的理解，提出了许多新问题。GRB的无线电观测独特地探测了爆炸的能量和环境。但是，目前在无线电频带中仅检测到30％的突发。使用即将到来的敏感望远镜进行的无线电观测可能会显着增加样本大小，并使人们可以在更长的时间内跟踪各个脉冲，并且能够回答与真实量热法，反向冲击发射以及大质量环境有关的一些重要问题。恒星在早期的宇宙中以GRB的形式爆炸。
