软γ重复源与重复快速射电暴的统计相似性

Statistical similarity between soft gamma repeaters and the repeating fast radio bursts

Yu Sang, Hai-Nan Lin

摘要:

我们研究了软γ中继站SGR 1935+2154的统计性质。我们发现,持续时间,等待时间,注量和通量的累积分布可以很好地拟合弯曲幂律。此外,持续时间,等待时间,通量和通量的起伏的概率密度函数很好地遵循Tsallis $q$ -高斯分布。$q$值在不同的时间尺度区间内保持稳定,表明爆发具有尺度不变的结构。这些特征与重复快速射电暴FRB 121102的性质非常相似,表明软伽马重复源和重复快速射电暴之间存在潜在的联系。

英文摘要:

We study the statistical properties of the soft gamma repeater SGR 1935+2154. We find that the cumulative distributions of duration, waiting time, fluence and flux can be well fitted by bent power law. In addition, the probability density functions of fluctuations of duration, waiting time, fluence and flux well follow the Tsallis $q$-Gaussian distribution. The $q$ values keep steady for different temporal scale intervals, indicating a scale-invariant structure of the bursts. Those features are very similar to the property of the repeating fast radio burst FRB 121102, indicating the underlying association between the origins of soft gamma repeaters and repeating fast radio bursts.
