[40.03] Radio Observations of Nuclear Starbursts in NGC\,6946, IC\,342, and NGC\,2903

A. Cox (U. Iowa), A. Watson (New Mexico State U.), E. Wilcots (U. Wisconsin)

We present sub-arcsecond images at 6\,cm and 2\,cm of the central regions of three nuclear starburst galaxies: NGC\,6946, IC\,342, amp;\ NGC\,2903. All three galaxies have multiple point sources at radio wavelengths. In two of these galaxies, IC\,342 and NGC\,2903, the majority of the radio sources appear to lie along a ring a few arcseconds from the galaxy center. We derive flux densities and radio spectral indices, discuss the nature of the point sources, and compare the thermal and non-thermal components of the radio continuum emission. Star-formation rates are derived and compared with previously published results.
