| Abstract: |
We describe a sensitive targeted search campaign at Parkes to find faint young radio pulsars using the center beam of the 20-cm multibeam receiver. The high frequency of the receiver mitigates scattering effects which can dominate profiles of distant pulsars at low frequencies and prevent detection. The targets included several composite supernova remnants (SNRs), two fast X-ray pulsars, long-period anomalous X-ray pulsars, and a soft gamma repeater. The sensitivity limits in this search are significantly better than those previously reported for these objects. We have discovered three new radio pulsars, two of which are not associated with the target objects. The third pulsar, PSR J1713-3949, is possibly associated with SNR G347.3-0.5; the estimated ages and distances of the two objects are consistent, but a more significant positional coincidence must be established with the central X-ray source in the SNR through pulsar timing to confirm or refute the association. |
