Parkes observations for project P1101 semester 2021OCTS_18

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 study emission properties, fluence distributions and polarisation properties over an extremely wide bandwidth with high sensitivity.

我们提出利用帕克斯射电望远镜（Parkes）的超宽带宽系统（UWL），对活跃性极强的重复快速射电暴FRB 190520开展每两周一次的监测。当前观测结果表明，FRB 190520不仅是帕克斯射电望远镜可观测到的最为活跃的快速射电暴，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设备。通过本观测项目，我们预期将探测到FRB 190520的大量爆发样本；同时，我们将与500米口径球面射电望远镜（FAST）合作，依托高灵敏度在超宽带宽范围内对该暴的辐射特性、能流分布以及偏振特性展开研究。
