Parkes observations for project P1121 semester 2021APRS_01

This project aims to obtain simultaneous multi-frequency full-polarisation observations of mode-switching pulsars to explore a novel method to estimate the charged current density based on the work by Hibschman & Arons (2001) and to investigate the remarkable frequency-dependent behaviour of the mode-separated profile shape of PSR B1822-09 and expand to the other moding pulsars. This dataset will allow us to investigate and compare between the modes subpulse modulation, profile’s shape and intensity, and polarisation position angle in both aspects of time and frequency evolution. Using Parkes and UWL, this dataset will provide more insights in understanding mode-switching pulsars and the pulsar’s magnetosphere in general.

这个项目旨在获取模式转换脉冲星的同步多频段全极化观测数据，以基于Hibschman & Arons（2001）的研究探索一种估算带电电流密度的新方法，并研究PSR B1822-09的模式分离轮廓形状显著的频率依赖行为，进而扩展到其他模式转换脉冲星。该数据集将使我们能够从时间演化和频率演化两个维度，研究并比较不同模式下的子脉冲调制、轮廓形状与强度，以及极化位置角。利用Parkes和UWL，该数据集将为理解模式转换脉冲星及脉冲星磁层（magnetosphere）的整体特性提供更深入的见解。
