Abstract

In this paper we present the optical identifications of the 1.4 GHz radio sources detected in the VIRMOS VLA Deep survey. Using optical (U, B, V, R and I) data, we found an optical identification for 718 of the 1054 radio sources. From the analysis of a color-colour diagram, we find that the median (V−I)_AB colour of the galaxies which show radio emission is redder than the median (V−I)_AB colour of the radio-quiet galaxies. This result suggests a higher redshift for the radio sources in comparison to the radio-quiet galaxies with similar optical magnitude at least in the magnitude slice 20<I _AB<22.
