RADIO POLARIZATION OBSERVATIONS OF G319.9–0.7: A BOW-SHOCK NEBULA WITH AN AZIMUTHAL MAGNETIC FIELD POWERED BY PULSAR J1509–5850

RADIO POLARIZATION OBSERVATIONS OF G319.9–0.7: A BOW-SHOCK NEBULA WITH AN AZIMUTHAL MAGNETIC FIELD POWERED BY PULSAR J1509–5850

We report radio polarization observations of G319.9−0.7 (MSC 319.9–0.7) at 3 and 6 cm obtained with the Australia Telescope Compact Array. The source shows a highly elongated morphology with the energetic pulsar J1509−5850 located at the tip. We found a flat radio spectrum of index α = −0.26 ± 0.04 …
