Parkes observations for project P885 semester 2021APRS_05

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 exciting recent results with UWL motivate an increased monitoring cadence to once weekly.

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，以追踪它们的自转、流量密度以及偏振特性。这项极具突破性的UWL观测能力，为厘清磁星至今仍不明朗的射电辐射机制提供了全新机遇。这一研究前景已得到近期后续观测结果的佐证：针对休眠10年后重新活跃的射电磁星XTE J1810-197，以及最新发布的磁星Swift J1818.0-1607，我们借助UWL已取得了令人振奋的阶段性成果，这也推动我们将对这两颗磁星的监测频次提升至每周一次。
