摘要
We have completed a search for radio pulsars using the Parkes 64m telescope, covering similar to 4500 deg(2) between 15 degrees and 30 degrees from the Galactic plane. Each pointing was observed for 265s with the 13-beam multibeam system at a frequency of 1374 MHz. The signal from each beam was processed by a 96-channel filterbank and sampled every 125 mu s, with a bandwidth of 288 MHz. This strategy affords rapid sky coverage and good sensitivity to pulsars with periods as short as 1 ms, whose existence would constrain the neutron star equation of state. Data were analyzed using the workstation cluster at the Swinburne Centre for Astrophysics and Supercomputing. This effort has yielded 26 new pulsars, including seven recycled pulsars. Taken together with the previous Swinburne Intermediate Latitude Pulsar Survey, a total of 95 new pulsars were found over nearly 7500 deg(2) of sky between 5 degrees and 30 degrees from the plane of the Galaxy. This large sample of newly discovered objects contains no young pulsars.
