A 5-GHz survey of bright Southern elliptical and S0 galaxies.
Abstract
The Parkes 64-m telescope has been used in a 5.0-GHz survey of 181 Southern E and S0 galaxies from the Reference catalogue of bright galaxies. Of the 39 detections above the nominal limit of 12 mJy, 15 are new, several have radio spectra indicating membership in the active class, and two have shown intensity variations at centimeter wavelengths. The results of this survey combined with results from earlier surveys of lower sensitivity suggest that only about 40 per cent of the E/S0 galaxies in the Reference catalogue have a flux density at 5 GHz exceeding 1 mJy.
