The Parkes Multi-beam Pulsar Survey (PMPS) was a large survey
undertaken between 1997 and 2002 with the Parkes 64m radio-telescope, Murriyang.
The original processing of the data discovered over 600 new pulsars, almost doubling
the number of pulsars known at the time.
Since then, computers have become more powerful, and processing algorithms more
sophisticated, and the data-set has been re-analysed several times, discovering
another 200-odd pulsars.
Sengar et al. have reprocessed the PMPS data again, using a new
GPU-accelerated search pipeline optimised for discovering narrow-duty
cycle pulsars, discovering another 37 pulsars. While 19 of these have
also been independently discovered in more recent pulsar surveys, 18
are exclusive to only the Parkes Multibeam Pulsar Survey data.
An ADAP last week showed the average pulse profiles of 9 of the newly
discovered pulsars -- today's image shows the other half, and illustrates
the power of the new search in finding narrow pulses. Each pulse profile consists of 256 bins and
covers one full phase (from zero to one) at 1.372 GHz. The peak of the
pulse profile of each pulsar has been centred at phase 0.5. The
y-axis shows the normalised flux density. The current name of the
pulsar, its rounded-off spin period (in milliseconds), and the DM (in
pc/cm^3) are also given for each pulsar.
