论文摘要
FRB〜121102是显示重复的第一个快速无线电爆发（FRB）。自2012年发现以来，已经从消息来源发现了200多个爆发。这些爆发表现出各种各样的光谱和时间特征，有关其起源和形式的许多问题仍未得到解答。在这里，我们提出了使用Jodrell Bank观测员的Lovell望远镜检测到的FRB 121102的无线电爆发样本。我们展示了四个爆发的示例，这些爆发显示了特殊的光谱时间特征，并将其与在其他观测值中检测到的Frb 〜121102的爆发的特性进行了比较。我们报告了一个前体爆发，与主爆发相距仅17毫米，这是迄今为止两次单独的爆发之间最短的分离。我们还提供了该广告系列中FRB〜121102所有检测的数据访问权限。
FRB~121102 was the first Fast Radio Burst (FRB) that was shown to repeat. Since its discovery in 2012, more than two hundred bursts have been detected from the source. These bursts exhibit a diverse range of spectral and temporal characteristics and many questions about their origin and form remain unanswered. Here, we present a sample of radio bursts from FRB 121102 detected using the Lovell telescope at Jodrell Bank Observatory. We show four examples of bursts that show peculiar spectro-temporal characteristics and compare them with properties of bursts of FRB~121102 detected at other observatories. We report on a precursor burst that is separated by just 17~ms from the main burst, the shortest reported separation between two individual bursts to date. We also provide access to data for all the detections of FRB~121102 in this campaign.
