| Abstract : | The X-ray source CXOU J163802.6-471358 shows an extended ~40 arcsec trail from a compact source and is thought to be a pulsar wind nebula (PWN). We observed this source with GMRT at 330 and 1390 MHz, which reveal a remarkable linear radio trail of about 90 arcsec in extent. The radio trail points back to the supernova remnant (SNR) G338.1+0.4, about 50 arcmin from CXOU J163802.6-471358. Associating it with this remnant would, however, require a very large velocity for the pulsar. There are no Galactic SNRs known close to the PWN and radio trail. No pulsar has yet been identified in CXOU J163802.6-471358, but if one could be found, this would allow more quantitative studies of the PWN and radio trail (For further details, please refer to http://arxiv.org/abs/2310.10341). |
