Parkes observations for project P1183 semester 2023APRS_05

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.

一个新的高能重复快速射电暴（FRB, Fast Radio Burst）20220529可被FAST与Parkes望远镜共同观测，且同步观测时长可达一小时。我们利用Parkes UWL的绿色观测时间对该源进行了观测，共探测到21个暴。其中两个暴具有对应的FAST同步观测数据，仅有一个暴拥有四极化（4-polarization）数据集且亮度足以分析其偏振特性。因此，我们建议继续使用具有高时间分辨率和四极化观测能力的Parkes UWL对FRB 20220529源进行监测。拟开展的新观测旨在：（1）通过Parkes UWL探测更多具有全偏振信息的暴；（2）探测更多可与FAST同步观测的暴；（3）利用Parkes与FAST同步观测到的更多暴研究辐射谱；（4）借助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。
