论文摘要
我们报告了加拿大氢强度映射实验的快速无线电爆发后端（Chime/frb）的发现，发现了七个新的银河脉冲星。这些来源首先是通过钟/frb中的单个脉冲鉴定的，然后加上钟声/脉冲星。四个来源似乎是旋转的无线电瞬变（RRAT），类似脉冲星的源具有偶尔的单个脉冲发射，具有基础周期性。在这四个来源中，有三个检测到的期限范围从220毫秒到2.726 s。三个来源具有更多的持久性，但仍然间歇性发射，可能是间歇性或无效的脉冲星。我们已经确定了后三个的相位交连时解决方案。这七个来源是先前未知的银河系来源，它具有钟声/FRB，并突出了快速无线电爆发检测工具的潜力，以搜索间歇性的银河无线电源。
We report the discovery of seven new Galactic pulsars with the Canadian Hydrogen Intensity Mapping Experiment's Fast Radio Burst backend (CHIME/FRB). These sources were first identified via single pulses in CHIME/FRB, then followed up with CHIME/Pulsar. Four sources appear to be rotating radio transients (RRATs), pulsar-like sources with occasional single pulse emission with an underlying periodicity. Of those four sources, three have detected periods ranging from 220 ms to 2.726 s. Three sources have more persistent but still intermittent emission and are likely intermittent or nulling pulsars. We have determined phase-coherent timing solutions for the latter three. These seven sources are the first discovery of previously unknown Galactic sources with CHIME/FRB and highlight the potential of fast radio burst detection instruments to search for intermittent Galactic radio sources.
