cds-question@unistra.frradio-sourcesquasarsactive-galactic-nucleiredshiftedThe dependence of the turnover frequency on the linear size is presented for a sample of Giga-hertz Peaked Spectrum and Compact Steep Spectrum radio sources derived from complete samples. The dependence of the luminosity of the emission at the peak frequency with the linear size and the peak frequency is also presented for the galaxies in the sample. The luminosity of the smaller sources evolve strongly with the linear size. Optical depth effects have been included to the 3D model for the radio source of Kaiser to study the spectral turnover. Using this model, the observed trend can be explained by synchrotron self-absorption. The observed trend in the peak-frequency-linear-size plane is not affected by the luminosity evolution of the sources.2016MNRAS.458.3786Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/3786CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/131/303 : GHz-Peaked-Spectrum radio sources (Stanghellini+ 1998)J/A+A/363/887 : High frequency peakers.
