Rejep et al. have investigated the emission properties of PSR
J1727−2739, which has a mean pulse profile consisting of two main
components, by analysing single-pulse observations made using the
Parkes 64-m radio telescope, Murriyang. Rejep et al. used publicly
available data from the Parkes Pulsar Data Archive from observations
were carried out over 5 epochs between April and October 2014 with the
center beam of the 20cm multibeam receiver. Previous studies reveal that
PSR J1727−2739 exhibits both nulling and subpulse drifting, and Rejep
et al. confirm the nulling fraction is about 66%. In addition to the
previously known subpulse drifting in the leading component, they also
explore the drifting properties for the trailing component. The
figure above shows the pulse energy variations with time for
observations in 2014 April, which shows many blocks of consecutive
strong pulses separated by frequent nulls.
The paper has been published in
Monthly Notices of the Royal Astronomical Society.
