P. Abstract The barred spiral galaxy M83 has been observed at 1465 and 4885 MHz with the VLA. The author finds significant emission in the bar, which is coincident with the narrow, linear, offset dust lanes visible there. This emission is nonthermal and moderately polarized. The author also finds spiral-arm structure, composed of H II regions and extended nonthermal features associated with observed dust lanes. These observations are consistent with the interpretation that the bar and nonthermal spiral-arm emission are due to shock enhancement of the underlying disk emission.
