Parkes observations for project P1101 semester 2021APRS_05

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.

我们提议借助帕克斯（Parkes）UWL系统，对极为活跃的重复快速射电暴FRB 190520开展每两周一次的监测。现有观测结果表明，FRB 190520不仅是帕克斯望远镜可观测到的最为活跃的快速射电暴（Fast Radio Burst，FRB），还在2至3 GHz频段展现出独特的辐射行为。这使得UWL系统成为开展该重复快速射电暴深入研究的理想仪器。通过本观测项目，我们预期将探测到FRB 190520的大量暴脉冲样本；同时我们将与500米口径球面射电望远镜（Five-hundred-meter Aperture Spherical radio Telescope，FAST）展开合作，搜寻潜在的周期性信号，并以高灵敏度在极宽带宽范围内研究其辐射特性。
