Description

Pulsars are highly linearly polarised sources whose polarimetry contains a wealth of information about the poorly-understood pulsar radio emission mechanism and the dynamics of the turbulent, relativistic plasma that gives rise to it. However, in order to leverage this information for scientific gain, the polarimetric response of the telescope must be precisely understood. While much fruitful work has been done to understand MWA polarimetry, the use of pulsars as potential polarimetric calibrators has not been fully explored. In this talk, I will discuss how the MWA's Voltage Capture System observations of bright pulsars might be used to improve existing calibration techniques by modelling, and correcting for, polarisation leakage.
