The discovery of many repeating fast radio bursts (FRBs) by the Canadian Hydrogen Intensity Mapping Experiment, the high rate of individual bursts, and the observation of repeat bursts from a bright FRB initially detected by the Australian Square Kilometre Array Pathfinder (ASKAP) suggest a significant population of repeating FRBs. Here, we analyze the rate distribution of this population using results from follow-up observations of the Commensal Real-time ASKAP Fast Transients Survey. Characterizing a repeating FRB by its burst rate R 0 above an energy of 10 38 erg, we consider a volumetric density Φ( R 0 ) with rate distribution ##IMG## [http://ej.iop.org/images/2041-8205/895/1/L22/apjlab8f99ieqn1.gif] {$d{\rm{\Phi }}\propto {R}_{0}^{\zeta }{{dR}}_{0}$} . We use maximum-likelihood methods to constrain ζ < −1.94 at 90% confidence. We discuss how this constraint can be used to limit different classes of p...

重复快速无线电爆炸人口的速率分布的测量：对祖细胞模型的影响。

加拿大氢强度图实验发现了许多重复的快速无线电脉冲（FRB），单个脉冲的发生率很高，并且观察到最初由澳大利亚平方公里阵列探路者（ASKAP）检测到的明亮FRB重复脉冲。大量重复FRB。在这里，我们使用商业实时ASKAP快速瞬态调查的后续观察结果来分析该人群的比率分布。通过高于10 38 erg的能量的爆发速率R 0来表征重复的FRB，我们考虑具有速率分布## IMG ##的体积密度Φ（R 0）[http://ej.iop.org/images/2041 -8205 / 895/1 / L22 / apjlab8f99ieqn1.gif] {$ d {\ rm {\ Phi}} \ propto {R} _ {0} ^ {\ zeta} {{dR}} _ {0} $}。我们使用最大似然方法以90％的置信度约束ζ<-1.94。
