Parkes Multibeam Pulsar Survey

(late 1990s radio survey in search of pulsars)

The Parkes Multibeam Pulsar Survey was an late 1990s astronomical survey to identify pulsars. It was carried out with the Parkes Observatory MB20 multibeam receiver, a grid of thirteen feed horns that defined a pattern of thirteen beams, which was developed for 21-cm line surveys. Detecting pulsars requires teasing out pulsar-specific-characteristics of their relatively weak signals from among all the sky's sources of radio, the weak requiring needing far too much integration time to discern pulses. The receiver, in addition to gathering data on thirteen portions of the sky simultaneously, provided enough of a spectral energy distribution to allow detection of pulsar candidates by their spectral index. Analysis of the data to extended into the 2000s and hundreds of pulsars were identified.
