1997A&A...321..105d Radio spectra of Gigahertz Peaked Spectrum radio sources. de Vries W.H., Barthel P.D., O'Dea C.P. Abstract. A well defined sample of 72 Gigahertz Peaked Spectrum radio sources is compiled, having turnover frequencies in the range of 0.5- 10GHz. Using this sample, the canonical GPS radio spectrum is constructed, which is found to have a constant shape, independent of AGN type, redshift or radio luminosity. A possible deficiency of low turnover frequencies at high redshift is found, which may reflect a physical mechanism where turnover frequency and radio luminosity are correlated. Key words: galaxies: active - radio continuum: galaxies - quasars: general
