标题： A Statistical Analysis of Crab Pulsar Giant Pulse Rates

摘要： 一些脉冲星已知会发射巨大脉冲，这些单个脉冲比平均脉冲明亮得多。其中就包括PSR J0534+2200，也称为蟹状脉冲星，这是一个年轻脉冲星，具有高巨大脉冲率。对蟹状脉冲星的长期监测为对其巨大脉冲及其影响过程进行统计研究提供了绝佳的机会，可能会提供关于其他发射明亮单脉冲中子星行为的见解。在这里，我们分析了一组从88小时每日观测中获得的24,985个蟹状脉冲星巨大脉冲数据，观测中心频率为1.55 GHz，由格林班克天文台的20米望远镜进行，数据分布在461天内。我们研究了比以前研究更高的频率下的折射闪烁效应，并比较了校正这种效应的方法。我们还寻找其他单脉冲源中出现的确定性模式，可能在几个旋转射电暂现源和快速射电暴中看到的周期性，以及像重复快速射电暴FRB121102中看到的巨大脉冲聚集现象。 显示英文摘要

摘要： A small number of pulsars are known to emit giant pulses, single pulses much brighter than average. Among these is PSR J0534+2200, also known as the Crab pulsar, a young pulsar with high giant pulse rates. Long-term monitoring of the Crab pulsar presents an excellent opportunity to perform statistical studies of its giant pulses and the processes affecting them, potentially providing insight into the behavior of other neutron stars that emit bright single pulses. Here, we present an analysis of a set of 24,985 Crab giant pulses obtained from 88 hours of daily observations at a center frequency of 1.55 GHz by the 20-meter telescope at the Green Bank Observatory, spread over 461 days. We study the effects of refractive scintillation at higher frequencies than previous studies and compare methods of correcting for this effect. We also search for deterministic patterns seen in other single-pulse sources, possible periodicities seen in several rotating radio transients and fast radio bursts, and clustering of giant pulses like that seen in the repeating fast radio burst FRB121102.
