Parkes observations for project P885 semester 2020OCTS_22

We propose to continue observing the magnetars 1E 1547.0?5408 and PSR J1622?4950 weekly, to track their rotation, flux density, and polarisation. The revolutionary UWL capabilities promise new opportunities to disentangle still mysterious radio emission mechanisms in magnetars. This promise is supported by the recent follow up of XTE J1810?197, again a radio magnetar after 10 years dormant, and of the hot-off-the-press magnetar Swift J1818.0?1607, for which our observations with the UWL receiver are providing unique and tantalizing measurements of radio spectrum and polarisation.

我们提议对磁星（magnetar）1E 1547.0−5408与PSR J1622−4950开展每周一次的持续观测，以监测其自转、流量密度与偏振特性。革命性的超宽频（UWL）观测能力为厘清磁星迄今仍笼罩神秘面纱的射电辐射机制提供了全新契机。这一前景已得到近期两项后续观测的支撑：其一为对休眠10年后重新活跃的射电磁星XTE J1810−197的观测，其二为对最新发现的磁星Swift J1818.0−1607的观测；针对后者，我们借助UWL接收机开展的观测正获取其射电频谱与偏振特性的独特且极具吸引力的测量数据。
