Parkes observations for project P885 semester 2021APRS_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 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开展每周一轮的持续观测，以追踪其自转参数、流量密度与偏振特性。凭借革命性的UWL观测能力，我们有望厘清磁星中至今仍笼罩在神秘面纱下的射电辐射机制。这一研究潜力得到了近期多项后续观测的佐证：包括对沉寂十载后再度活跃的射电磁星XTE J1810-197的观测，以及对新近发布的磁星Swift J1818.0-1607的观测；基于我们此前利用UWL取得的突破性研究成果，我们提议将对该天体的观测频次提升至每周一次。
