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.

我们建议利用帕克斯超宽带（UWL）系统对极活跃的重复暴源FRB~190520开展每两周一次的监测。当前观测结果显示，FRB~190520不仅是可通过帕克斯望远镜观测到的最活跃快速射电暴（FRB），还在2至3 GHz频段表现出独特的行为特征。这使得UWL成为对该重复快速射电暴进行深入研究的理想仪器。通过本项目，我们期望探测到FRB~190520的大量暴发现象样本；同时，与500米口径球面射电望远镜（FAST）合作，我们将搜索潜在的周期性，并在极宽的带宽范围内以高灵敏度研究其辐射特性。
