    An association between a long-period pulsar and an old supernova remnant (1993)
    In:  Other Sources
    Details
    Publication Date: 2019-08-28
    Description: A possible association between pulsar 2334 + 61, with a relatively long period of 0.5 s, and G114.3 + 0.3, a fairly old SNR is reported. The flat spectral index of -0.36 +/- 0.03 and large fractional polariazation suggest that the radio emission is powered by the pulsar. If so, the pulsar must have been born with a relatively short period of less than 100 ms. As the SNR is not particularly unusual morphologically, there might be many more such SNRs containing pulsars that are not beamed towards us.

    G359.23-0.92, the Mouse, a pulsar powered bow shock? (1995)
    In:  Other Sources
    Details
    Publication Date: 2019-08-27
    Description: We have discovered a faint X-ray object coincident with the head of the 'Mouse' (G359.23-0.82), a member of the rare class of axially symmetric radio nebula. Such objects are believed to be excited by a fast moving central source which supplies relativistic particles that emit the observed non-thermal radiation. The origin of most such objects and the Mouse in particular is obscure. We argue that the Mouse is the wake left by a young pulsar rather than an accreting binary, a popular model for this class. On phenomenological grounds we suggest that the Mouse is similar in some ways to the bow shock of the moderately young pulsar 1951+32 embedded in the supernova remnant CTB80. The rarity of Mouse-like nebulae is puzzling and can only be explained by assuming that most pulsars are in low density media.
