A radio supernova remnant associated with the young pulsar J1119-6127

We report on Australia Telescope Compact Array observations in the directio n of the young high magnetic-held pulsar J1119 - 6127. In the resulting ima ges we identify a nonthermal radio shell of diameter 15', which we classify as a previously uncataloged young supernova remnant, G292.2-0.5. This supe rnova remnant is positionally coincident with PSR J1119-6127, and we conclu de that the two objects are physically associated. No radio emission is det ected from any pulsar wind nebula (PWN) associated with the pulsar; our obs erved upper limits are consistent with the expectation that high magnetic-f ield pulsars produce radio nebulae that fade rapidly. This system suggests a possible explanation for the lack of an associated radio pulsar and/or PW N in many supernova remnants.
