Radio spectra of Gigahertz Peaked Spectrum radio sources.
DE VRIES W.H., BARTHEL P.D. and O'DEA C.P.
Abstract (from CDS):
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.
