Parkes observations for project P1183 semester 2023APRS_11

A new energetic repeating FRB 20220529 can be observed by both FAST and Parkes telescopes and the simultaneous observing time is up to one hour. We have observed this source using Parkes UWL green time and in total 21 bursts have been detected. Two bursts of them have the corresponding simultaneous FAST observations. Only one burst has 4-pol datasets and is bright enough to analyse the polarization properties. Therefore, we propose to continue the monitoring of the source of FRB 20220529 using the Parkes UWL with high-time resolution and 4-pol observation. The new proposed observation aims to: (1)detect more bursts by Parkes UWL with full polarization information; (2) detect more bursts by Parkes UWL with corresponding simultaneous FAST observations; (3) study the radiation spectrum by more bursts detected in simultaneous observations of Parkes and FAST; (4) study the burst microstructure using high time resolution datasets, and (5) study the frequency ranges changes of the repeating bursts.

新发现的高能重复快速射电暴（FRB）20220529可被500米口径球面射电望远镜（FAST）和Parkes望远镜共同观测，同步观测时长可达一小时。我们利用Parkes UWL的green time对该源进行了观测，共探测到21个暴。其中两个暴存在对应的同步FAST观测数据。仅有一个暴拥有四极化（4-pol）数据集，且亮度足以分析其偏振特性。因此，我们建议利用具备高时间分辨率和四极化观测能力的Parkes UWL，继续对FRB 20220529源进行监测。新的拟议观测旨在：（1）利用具备全偏振信息的Parkes UWL探测更多暴；（2）利用Parkes UWL探测更多存在同步FAST观测数据的暴；（3）通过Parkes与FAST同步观测中探测到的更多暴研究其辐射谱；（4）利用高时间分辨率数据集研究暴的微观结构；（5）研究重复暴的频率范围变化。
