VLA observations of Markarian 8 at 6 cm wavelength.
Abstract
VLA observations show that the irregular galaxy Markarian 8 consists of three radio components coincident with optical clumps. The radio spectra of the components are flat and their emission is probably thermal. The radio components are imbedded in a diffused envelope of nonthermal emission. The radio and optical structures of Markarian 8 are similar. Under the assumption of thermal emission, electron densities and ionized hydrogen masses contained in the components are calculated. The results indicate that the clumps may indeed be supergiant H II regions.
