Studies of the Crab Giant Pulses with the Murchison Widefield Array
MetadataShow full item record
This thesis is a study of giant pulses from the Crab pulsar. The giant pulses are short duration radio bursts consisting of complex superpositions of nanosecond- and microsecond-scale impulses. The short duration of these giant pulses imply broadband emission and very high brightness temperatures. We have investigated the broad band nature of the Crab giant pulses with the Murchison Widefield Array and Parkes radio telescope, as well as their spectral behaviour at low radio frequencies.

Knight, H.; Bailes, M.; Manchester, R.; Ord, Stephen; Jacoby, B. (2006)We have conducted a search for giant pulses from four millisecond pulsars using the 100 m Green Bank Telescope. Coherently dedispersed time series from PSR J0218+4232 were found to contain giant pulses of very short ...
Knight, H.; Bailes, M.; Manchester, R.; Ord, Stephen (2005)We have searched for microsecond-timescale broadband emission from a sample of 18 millisecond pulsars. Our study places strong limits on such emission from several millisecond pulsars and shows that it is only present in ...
Meyers, B.; Tremblay, S.; Bhat, N.; Shannon, R.; Kirsten, F.; Sokolowski, M.; Tingay, Steven; Oronsaye, S.; Ord, S. (2017)We report on simultaneous wideband observations of Crab giant pulses with the Parkes radio telescope and the Murchison Widefield Array (MWA). The observations were conducted simultaneously at 732 and 3100 MHz with Parkes, ...
