Parkes observations for project P885 semester 2020APRS_02

We propose to observe the magnetars 1E 1547.0-5408 and PSR J1622-4950\r\napproximately weekly, to track their rotation, flux density, and\r\npolarisation, as we have long been doing through this project. The\r\nrevolutionary UWL capabilities promise new opportunities to disentangle\r\nstill mysterious radio emission mechanisms in magnetars. This promise\r\nis supported by the recent follow up of XTE J1810-197, again a radio\r\nmagnetar after 10 years dormant, for which our observations with\r\nthe UWL receiver are providing unique and tantalizing measurements\r\nof its radio spectrum and polarisation.

本研究提议对磁星（magnetars）1E 1547.0-5408与脉冲星PSR J1622-4950开展约每周一次的观测，以追踪其自转特性、流量密度与偏振状态，一如我们长期以来通过本项目所开展的观测工作。
革命性的超宽频（UWL）观测能力，为解开磁星领域至今仍悬而未决的射电辐射机制之谜提供了全新契机。
这一潜力已得到XTE J1810-197近期后续观测的佐证：该源同样是一颗经历10年休眠后重新活跃的射电磁星，我们借助UWL接收机对其开展的观测，正提供关于其射电频谱与偏振特性的独特且极具价值的测量数据。
