Parkes observations for project P885 semester 2022OCTS_12

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、流量密度与偏振特性。1E 1547.0-5408刚刚在辐射特性与自转方面出现异常波动，针对此次事件的短期响应仍不明确。Swift J1818.0-1607目前仍处于高度活跃状态，其独特的UWL观测能力有望为探究磁星中仍未明晰的射电辐射机制提供新机遇。我们将以更低监测频次观测XTE J1818-197与刚刚停止辐射的PSR J1622-4950。本次观测申请总时长为18小时。
