Abstract (from CDS):

The faint radio supernova remnant SNR G315.9-0.0 is notable for a long and thin trail that extends outward perpendicular from the edge of its approximately circular shell. In a search with the Parkes telescope, we have found a young and energetic pulsar that is located at the tip of this collimated linear structure. PSR J1437-5959 has period P = 61 ms, characteristic age τc = P/(2P{dot}€ = 114 kyr, and spin–down luminosity E{dot}= 1.4 x1036erg/s. It is very faint, with a flux density at 1.4 GHz of about 75 muJy. From its dispersion measure of 549 pc/cm3, we infer d approx 8 kpc. At this distance and for an age comparable to tauc, the implied pulsar velocity in the plane of the sky is Vt= 300 km/s for a birth at the center of the SNR, although it is possible that the SNR/pulsar system is younger than taucand that Vt> 300 km/s. The highly collimated linear feature is evidently the pulsar wind trail left from the supersonic passage of PSR J1437–5959 through the interstellar medium surrounding SNR G315.9–0.0.
