Parkes observations for project P1101 semester 2022APRS_04

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.

本研究拟利用帕克斯UWL（Parkes UWL）系统，对活跃重复快速射电暴（Fast Radio Burst，FRB）190520开展每两周一次的监测。现有观测结果显示，FRB 190520不仅是帕克斯望远镜可观测到的活跃度最高的快速射电暴，还在2至3 GHz频段展现出独特的辐射特性。这使得帕克斯UWL系统成为开展该重复快速射电暴深度研究的理想仪器。通过本监测项目，我们预期将探测到FRB 190520的大量爆发事件样本；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）开展合作，依托极高的灵敏度，在超宽频段内对该暴的辐射特性、能流密度分布与偏振特性展开系统研究。
