Parkes observations for project P885 semester 2019APRS_14

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. As of\r\nthis week (8 Dec 2018), XTE J1810-197 is again a radio magnetar,\r\nafter 10 years dormant! (We have been observing it sporadically\r\nduring its low state waiting for such an event.) Its likely chaotic\r\nrotation will be better tracked in detail elsewhere, but weekly\r\nobservations with the UWL receiver will provide unique measurements\r\nof its radio spectrum and broad-band behaviour. Our observations\r\nprovide an important window into remarkably dynamic magnetar\r\nmagnetospheres, and characterise the conditions under which radio\r\nemission takes place therein, placing constraints on the emission\r\nmechanisms, which in at least some significant respects differ from\r\nthose of ordinary pulsars.
