Optical identifications of High Frequency Peakers
We present CCD observations of 13 objects from a complete sample of 55bright High Frequency Peaker (HFP) radio sources, and provide opticalidentification for 12 of them. Images in R and V filters have been usedto derive some additional information concerning the host of the radiosource. Three hosts are likely to be galaxies, one resulted slightlyextended, while the remaining 8 are likely distant quasars. Based onthese identifications and those available in the literature, we findthat the fraction of quasars in our HFP sample is significantly higherthan in samples of Compact Steep-Spectrum and GHz-Peaked Spectrum radiosources. Based on observations made with the Italian TelescopioNazionale Galileo (TNG) operated on the island of La Palma by the CentroGalileo Galilei of the CNAA (Consorzio Nazionale per l'Astronomia el'Astrofisica) at the Spanish Observatorio del Roque de los Muchachos ofthe Instituto de Astrofisica de Canarias.
