Parkes observations for project P885 semester 2018APRS_01

Full description

We propose to observe PSR J1622-4950 and 1E1547.0-5408 weekly, two\r
of three magnetars known to currently emit radio pulsations, to\r
track their rotation, flux density, and polarisation. Less frequently\r
we will monitor XTE J1810-197, which used to emit radio pulsations,\r
to be on the lookout for its revival - as just happened with PSR\r
J1622-4950, which turned on in April 2017 after more than 2 years dormant!\r
These observations yield a continuous record of torque, illuminating\r
the continued release of magnetic energy. Our broader aims are to\r
develop a better understanding of the dynamical behaviour of magnetar\r
magnetospheres, and to establish the conditions under which radio\r
emission takes place therein, in addition to characterising their\r
variable radio emission in order to place constraints on the emission\r
mechanisms, which in at least some respects differ from those of\r
ordinary pulsars.
