Abstract
We have carried out a sensitive search for young pulsars associated wi th supernova remnants using the 76-m Lovell radio telescope at Jodrell Bank. The observations were made at 606 MHz using a system with a ban dwidth of 8 MHz and a set noise temperature on cold sky of about 50 K. The survey targeted 33 remnants in the northern hemisphere and achiev ed a nominal sensitivity of similar to 1 mJY in most cases. Two pulsar s were discovered in the course of this survey and the known pul sar P SR B1952+29 was detected. The new pulsars, J0215+6218 and J1957+2831, were found during searches of the supernova remnants G132.7+1.3 and G6 5.1+0.6 respectively. Based on a statistical analysis of the present s ample of proposed pulsar-supernova remnant pairs, we conclude that at most 17 associations arp likely to be real. We find no strong evidence for a genuine association between either of the two newly discovered pulsars and their target supernova remnants.
