摘要
从2021年夏季开始，格陵兰射电中微子观测站（RNO-G）将通过探测格陵兰 summit station 周边冰体内粒子簇射的射电辐射，搜寻能量大于10 PeV 的天体物理中微子。我们展示了一项广泛的模拟研究，表明 RNO-G 将能够测量此类粒子簇射的能量，进而用于估计引发它们的入射中微子的能量。中微子相互作用的位置利用各通道间到达时间差确定，射电信号的电场采用一种基于信息场论的新方法进行重建。基于这些性质，可估计簇射能量。我们表明，在经过适度质量截断后，该方法对簇射能量对数的不确定度可达13%，并估计了由此对约束中微子能量的作用。本文提出的方法适用于所有类似的射电中微子探测器，例如拟议的 IceCube-Gen2 射电阵列。
