These observations have spatial (angular) resolutions of 30–720 pc (0.″07–0.″67) in a part of the spectrum that is likely to be optically thin. This allows us to estimate the size of the energetically dominant regions. We find half-light radii from 30 pc to 1.7 kpc. The 33 GHz flux density correlates well with the | | Free Keywords: | galaxies: active; galaxies: interactions; galaxies: starburst; radio continuum: galaxies | | External Publication Status: | published | | Document Type: | Article |
