Abstract

We present sensitive, high-resolution radio observations of the circumnuclear region of the barred spiral galaxy NGC 6951. These observations reveal a ring of radio emission with many discrete components and a marginally resolved nuclear component. We compare the radio ring with observations at other wavelengths, and discuss the nature of the compact radio components.
