Sub-mJy radio sources - A population of starburst galaxies at intermediate redshiftsOptical-infrared observations are used to show that the sub-mJy sources, discovered in deep radio surveys and responsible for the upturn in the radio source counts at sub-mJy levels, represent a population of star-forming galaxies at intermediate redshifts and with Mv between about -23 and -20. The very high frequency of line-emission, the very large incidence of galaxy mergers and interactions associated with these sub-mJy sources, and the good agreement between the sub-mJy radio source counts and the counts of starburst galaxies from deep IRAS surveys imply that these star-forming galaxies are in fact undergoing starbursts.
