Parkes observations for project P885 semester 2022OCTS_14

We request a continued modest monitoring cadence of once every 10 days for two radio magnetars, to track their rotation, flux density, and polarisation. 1E 1547.0-5408 has just suffered a 'hiccup' in radiative properties as well as in its rotation, and the near-term response to this event remains unclear. Swift J1818.0-1607 remains quite dynamic, and the unique UWL capabilities promise new opportunities to probe still mysterious radio emission mechanisms in magnetars. We will observe XTE J1810-197 and PSR J1622-4950, which has just ceased emission, less frequently. The overall request is 18 hours.

我们申请对两颗射电磁星（radio magnetar）维持每10天一次的适度监测频次，以追踪其自转、流量密度与偏振（polarisation）特性。1E 1547.0-5408的辐射特性与自转刚刚出现了一次‘抖动’，目前针对该事件的短期响应机制仍不明确。斯威夫特J1818.0-1607仍处于高度活跃状态，其独特的UWL观测能力为探索磁星中迄今仍神秘莫测的射电辐射机制提供了新的契机。我们将以更低的监测频率对XTE J1818-197与刚刚停止射电辐射的PSR J1622-4950进行观测。本次观测申请总时长为18小时。
