Parkes observations for project P1040 semester 2020OCTS_08

We have re-processed all the observations in the Parkes pulsar data archive obtained during the first four years of the Parkes multibeam receiver and have discovered two new fast radio bursts (FRBs) and five single pulse candidates (SPCs) from unknown sources, but with Galactic dispersion measures. These signals were only detected in a single beam of the receiver suggesting that they are unlikely to be terrestrial. There are no known pulsars in the pointing direction of the five SPCs and therefore are likely giant pulses from currently unknown pulsars. Using the Ultra Wideband Low (UWL) receiver we have opportunity to detect repeating signals from the two FRBs and to confirm the five SPCs. Our previous observations have obtained new detections for one of these targets and therefore confirming that source. Therefore we propose for more observation in an attempt to confirm the remainder and to study the newly discovered source.

我们重新处理了帕克斯多波束接收器前四年观测所得的帕克斯脉冲星数据档案中的所有观测结果，发现了两个新的快速射电暴（FRBs）和五个来自未知源的单脉冲候选体（SPCs），且这些信号具有银道弥散量度。这些信号仅在接收器的单个波束中被探测到，表明它们不太可能源自地球。五个SPCs的指向方向上不存在已知脉冲星，因此它们很可能是来自目前未知脉冲星的巨脉冲。利用超宽带低频（UWL）接收器，我们有机会探测到这两个FRB的重复信号，并确认这五个SPCs。我们此前的观测已对其中一个目标获得了新的探测结果，从而确认了该源的存在。因此，我们提议开展更多观测，以期确认剩余目标并研究新发现的源。
