论文摘要
重复的快速无线电爆发（FRB）与脉冲星的巨型脉冲（GPS）之间存在一些相似之处。为了探索它们之间的可能关系，我们使用重复FRB 121102和螃蟹脉冲星的GP的观察结果研究了这两种现象的累积能量分布。我们发现，GPS的幂律坡度（带有Fluence $ \ geq $ 130 JY MS）为$ 2.85 \ PM0.10 $。 FRB 121102的能量分布可以通过光滑的破碎幂律函数很好地安装。对于上方的FRB 121102的爆发（1.22 $ \ times 10^{37} $ erg），最合适的坡度为$ 2.90 _ { - 0.44}^{+0.55} $，类似于与GPS的索引在同一观察频率（$ \ sim $ 1.4 GHZ）。我们进一步讨论了超级GPS模型框架中重复FRB 121102的物理起源。而且我们发现，涉及毫秒脉冲星的超级GPS模型是可行的，并且对解释FRB 121102的偏爱是可行的，尽管Magnetar爆发模型更为流行。
There are some similarities between bursts of repeating fast radio bursts (FRBs) and giant pulses (GPs) of pulsars. To explore possible relations between them, we study the cumulative energy distributions of these two phenomena using the observations of repeating FRB 121102 and the GPs of Crab pulsar. We find that the power-law slope of GPs (with fluence $\geq$130 Jy ms) is $2.85\pm0.10$. The energy distribution of FRB 121102 can be well fitted by a smooth broken power-law function. For the bursts of FRB 121102 above the break energy (1.22 $\times 10^{37}$ erg), the best-fitting slope is $2.90_{-0.44}^{+0.55}$, similar to the index of GPs at the same observing frequency ($\sim$1.4 GHz). We further discuss the physical origin of the repeating FRB 121102 in the framework of the super GPs model. And we find that the super GPs model involving a millisecond pulsar is workable and favored for explaining FRB 121102 despite that the magnetar burst model is more popular.
