Parkes observations for project P885 semester 2021APRS_14

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（polarisation）特性。革命性的UWL观测能力为解开磁星至今仍扑朔迷离的射电辐射机制之谜提供了全新契机。这一研究前景得到了近期多项后续观测的佐证：包括此前休眠10年的射电磁星XTE J1810-197的跟进观测，以及新近发现的磁星Swift J1818.0-1607的相关研究——基于我们此前利用UWL获得的突破性成果，我们提议将对该天体的监测频次提升至每周一次。
