Parkes observations for project P1101 semester 2021OCTS_16

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.

我们建议使用帕克斯超宽带系统（Parkes UWL system）对极活跃的重复暴源FRB~190520开展每两周一次的监测。我们当前的观测结果表明，FRB~190520不仅是帕克斯望远镜可观测范围内最活跃的快速射电暴（FRB），还在2至3 GHz频段呈现独特行为。这使得UWL成为开展该重复暴源深度研究的理想设备。通过本项目，我们预计能探测到FRB~190520的大量爆发样本；并与FAST望远镜合作，在极宽的带宽范围内以高灵敏度研究其辐射特性、流量密度分布及偏振特性。
