Cosmological Evolution of Average Continuum Spectra of Radio Sources at Z >2 Redshifts

详细

A new method is proposed for studying the population of distant radio sources. It is based on building the average continuum radio spectrum for objects located within the given redshift interval. In this paper the redshift bin size dz is set equal to 0.1. The data about the average spectra can theoretically be used to study the distribution of the large-scale structure and the features of its formation. On the practical side the average spectra at different z can be used to simulate the distribution of radio sources, which is required in various computational tasks. The change of the form of the spectrum at different z is indicative of the cosmological evolution of the population of radio sources.
