[10.09] A New Sample of Candidate for Pulsar/Supernova Remnant Associations

D.A Leahy (U. Calgary), W. Tian (U. Calgary & Nat'l Astronomical Obs. of China)

Abstract: We list a sample of 46 pairs of Pulsar (PSR) and Supernova Remnant (SNR) associations which have been suggested from over 230 SNRs and 1300 PSRs. At least half of them are still in active debate. We analyse factors which may result in the deficit of associations. Considering recent observational progress which suggests that PSR/SNR associations may be older than previously documented by an order of magnitude, that the characteristic age of a pulsar may be greatly different from its true age, and that a neutron star birth-place may be considerably offset from the geometrical centre of its associated SNR, we give a new sample of candidates for PSR/SNR associations. Comparing with previous searches for PSRs in SNRs or SNRs around PSRs, candidates which have been previously confirmed are taken out of our sample. Pulsars with characteristic ages above 1000kyr are also removed from the sample.

We acknowledge the Chinese Scholarship Council and the Natural Sciences and Engineering Research Council of Canada for support.
