Parkes observations for project P1183 semester 2023APRS_13

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.

高能重复快速射电暴FRB 20220529（Fast Radio Burst 20220529）可被500米口径球面射电望远镜（Five-hundred-meter Aperture Spherical Telescope, FAST）与帕克斯望远镜（Parkes Telescope）共同观测，二者同步观测的单次时长可达1小时。
我们曾利用帕克斯UWL的绿色通道观测时段对该源开展观测，总计探测到21个暴。其中2个暴拥有同步FAST观测数据，仅1个暴具备四偏振（4-pol）数据集且亮度足够用于偏振特性分析。
因此，我们提议借助帕克斯UWL设备开展高时间分辨率与四偏振观测，持续对FRB 20220529源进行监测。本次拟实施的观测目标如下：
1. 利用帕克斯UWL设备探测更多携带完整偏振信息的暴源；
2. 利用帕克斯UWL设备探测更多可同步开展FAST观测的暴源；
3. 依托帕克斯与FAST同步观测获得的更多暴源数据，研究其辐射光谱特性；
4. 利用高时间分辨率数据集分析暴源的微结构；
5. 研究重复暴的频率范围变化规律。
