论文摘要

自2018年秋季以来,加拿大氢强度映射实验(Chime)的脉冲星后端已经监测了北部天空中数百个已知的脉冲星,为研究脉冲星排放的时间变化提供了丰富的数据集。使用匹配的过滤技术,我们首次报告了五个脉冲星的行为以及九个脉冲星的模式切换。仅观察到其中一个脉冲星显示出空白的信号和调度信号。这些新的无效切换脉冲星似乎来自具有相对较长自旋时期的人群,与文献中的先前发现一致。

The Pulsar backend of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has monitored hundreds of known pulsars in the northern sky since Fall 2018, providing a rich data set for the study of temporal variations in pulsar emission. Using a matched filtering technique, we report, for the first time, nulling behaviour in five pulsars as well as mode switching in nine pulsars. Only one of the pulsars is observed to show both nulling and moding signals. These new nulling and mode switching pulsars appear to come from a population with relatively long spin periods, in agreement with previous findings in the literature.
