Parkes observations for project P885 semester 2022OCTS_03

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 magnetars）维持每10天一次的适度监测频次，以追踪其自转、流量密度与偏振特性。编号为1E 1547.0-5408的射电磁星刚刚在辐射特性与自转两个维度均出现了一次"颤振"，目前针对该事件的短期响应机制仍不明确。Swift J1818.0-1607至今仍表现出极强的动力学活性，其独特的UWL观测能力为探究磁星中至今仍充满谜团的射电辐射机制提供了全新契机。我们将降低对XTE J1810-197与刚刚停止辐射的脉冲星PSR J1622-4950的观测频次。本次观测申请的总时长为18小时。
