Parkes observations for project P1101 semester 2021APRS_03

We propose to carry out fortnightly monitoring of a very active repeater, FRB~190520, with the Parkes UWL system. Our current observations show that FRB~190520 is not only the most active FRB that can be observed with Parkes, but also shows unique behaviour at 2 to 3 GHz frequency. This makes UWL the ideal instrument to carry out in-depth studies of this repeating FRB. With this program, we expect to detect a large sample of bursts from FRB~190520, and in collaboration with the FAST telescope we will search for potential periodicity and study emission properties over an extremely wide bandwidth with high sensitivity.

我们建议使用帕克斯超宽带（Parkes UWL）系统，对极活跃的重复快速射电暴（Fast Radio Burst, FRB）源FRB~190520开展每两周一次的监测。目前观测结果显示，FRB~190520不仅是帕克斯望远镜可观测范围内最活跃的FRB，还在2至3 GHz频段呈现出独特的行为特征。这使得UWL成为对该重复FRB进行深入研究的理想仪器。通过本项目，我们预计将探测到FRB~190520的大量爆发样本；并与500米口径球面射电望远镜（Five-hundred-meter Aperture Spherical Telescope, FAST）合作，搜索潜在周期性特征，同时以高灵敏度在极宽的带宽范围内研究其辐射特性。
