Parkes observations for project P885 semester 2019OCTS_01

We propose to observe the magnetars 1E 1547.0-5408 and PSR J1622-4950\r\napproximately weekly, to track their rotation, flux density, and\r\npolarisation, as we have been doing through this project. Also, as\r\nof late 2018, XTE J1810-197 is again a radio magnetar after 10 years\r\ndormant! Its chaotic rotation is better tracked in detail elsewhere,\r\nbut weekly observations with the UWL receiver are already providing\r\nunique measurements of its radio spectrum and broad-band behaviour.\r\nOur observations provide an important window into remarkably dynamic\r\nmagnetar magnetospheres, and characterise the conditions under which\r\nradio emission takes place therein, placing constraints on the\r\nemission mechanisms, which in at least some significant respects\r\ndiffer from those of ordinary pulsars.

我们提议对磁星（magnetar）1E 1547.0-5408与脉冲星（Pulsar，缩写PSR）J1622-4950开展约每周一次的观测，以追踪它们的自转、流量密度（flux density）与偏振（polarisation），一如本项目此前开展的观测工作。
此外，截至2018年末，XTE J1810-197在休眠10年后再度成为射电磁星！
尽管其混沌自转的详细追踪可在其他研究中完成，但借助UWL接收机（UWL receiver）开展的每周观测已能为其射电频谱与宽频行为提供独特的实测数据。
本团队的观测为探究极具动态性的磁星磁层提供了重要窗口，同时刻画了其内部射电辐射产生的环境条件，从而对辐射机制施加约束——该机制在至少若干关键层面与普通脉冲星的辐射机制存在显著差异。
