Scientific paper

Deep R band CCD images of 14 radio sources which have simple convex radio spectra with steep spectral indices at high frequencies and spectral turnovers near 1 GHz are presented. Of the 12 optically faint GHz-peaked spectrum (GPS) sources, there are eight new or revised identifications with magnitudes ranging from 20 to 23. The results agree with the hypothesis that optically faint GPS sources are a mixed group of objects, and based on the current imaging data they are preferentially faint radio galaxies.
