A search for millisecond pulsars at high galactic latitude

We are conducting a search for radio pulsars using the Parkes 64 m telescope, covering similar to4500 square degrees in the galactic latitude range 15degrees < \b\ < 30degrees. Each pointing is observed for 265 s with the 13-beam multibeain system at a frequency of 1374 MHz. The signal from each beam is processed by a 2 x 96 channel filterbank sampled every 125 mus, with a bandwidth of 288 MHz. This strategy affords rapid sky coverage and good sensitivity to pulsars with periods as short as similar to1 ms, whose existence would constrain the neutron star equation of state. Data are analyzed offline using the workstation cluster at the Swinburne Centre for Astrophysics and Supercomputing. Analysis of similar to3000 square degrees of the survey has been completed, yielding 22 new pulsars including five recycled pulsars. Three of these objects have great potential for high precision timing experiments, and one has an unusual massive white dwarf companion.
