Abstract
A radio image that covers the Hubble deep field and flanking fields has been made using the VLA for 50 hr at a frequency of 8.4 GHz, a resolution of 6", and a 4.3 σ detection level of 12.2 μJy. All six radio sources detected in the deep field are identified with galaxies brighter than I = 24 mag, based on a radio/optical coincidence better than 1". In the flanking fields 8 of 12 sources are identified with galaxies 19 to 25 mag. The identifications are preferentially with red elliptical galaxies and early-type spiral galaxies. Several galaxies show distortions that suggest interaction.
