The Thousand-Pulsar-Array programme on MeerKAT VII: Polarisation
  properties of pulsars in the Magellanic Clouds
  The Magellanic Clouds are the only external galaxies known to host radio
pulsars. The dispersion and rotation measures of pulsars in the Clouds can aid
in understanding their structure, and studies of the pulsars themselves can
point to potential differences between them and their Galactic counterparts. We
use the high sensitivity of the MeerKAT telescope to observe 17 pulsars in the
Small and Large Magellanic Clouds in addition to five foreground (Galactic)
pulsars. We provide polarization profiles for 18 of these pulsars, improved
measurements of their dispersion and rotation measures, and derive the mean
parallel magnetic field along the lines of sight. The results are broadly in
agreement with expectations for the structure and strength of the magnetic
field in the Large and Small Magellanic Clouds. The Magellanic Cloud pulsars
have profiles which are narrower than expected from the period-width
relationship and we show this is due to selection effects in pulsar surveys
rather than any intrinsic difference between the population of Galactic and
Magellanic objects.
