A YOUNG, GLITCHING PULSAR NEAR THE DIRECTION OF W28

Timing observations of PSR B1758-23 (PSR J1801-23) made over a 6 yr period using the 64 m Parkes radio telescope and the 76 m Lovell radio telescope show that this pulsar is young and is located close to the edge of the supernova remnant W28. The pulsar's characteristic age of 58,000 yr is consistent with the estimated remnant age, but the large observed dispersion of the pulsar signal is difficult to reconcile with the independently estimated remnant distance. PSR B1758-23 has glitched three times during our observations, in keeping with the trend of high glitch activity in younger pulsars.
