Parkes observations for project P1101 semester 2022APRS_01

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.

我们提议利用帕克斯超宽频带（Ultra-Wideband, UWL）系统，对快速射电暴（Fast Radio Burst, FRB）FRB~190520这一活跃重复暴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最为活跃的快速射电暴，还在2至3吉赫兹（GHz）频段展现出独特的行为特征。这令UWL系统成为开展该重复快速射电暴深度研究的理想工具。通过本项目，我们预计将从FRB~190520中探测到大量爆发事件样本，并将与500米口径球面射电望远镜（Five-hundred-meter Aperture Spherical radio Telescope, FAST）合作，在极宽带宽范围内以高灵敏度研究其辐射特性、能注量分布与偏振特性。
