Parkes observations for project P1101 semester 2021APRS_07

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.

我们提议利用帕克斯望远镜的UWL系统，对极活跃的重复快速射电暴（Fast Radio Burst，FRB）~190520开展每两周一次的监测。当前观测结果表明，FRB~190520不仅是帕克斯望远镜可观测到的最为活跃的快速射电暴，同时在2至3吉赫（GHz）频段展现出独特的辐射特性。这使得UWL系统成为开展该重复快速射电暴深度研究的理想仪器。依托本观测项目，我们预计将探测到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 Telescope，FAST）合作，搜寻其潜在周期性，并以高灵敏度在极宽带宽范围内研究其辐射特性。
