Number Counts and Spectral Distribution of Radio Sources at Centimeter Wavelengths

  • I. I. K. Pauliny-Toth (a1), K. I. Kellermann (a1) and M. M. Davis (a1)

Abstract

The results of a survey of selected regions of sky made at a frequency of 5 GHz, and of measurements of the spectral index distributions for sources selected from low frequency surveys are presented. The source counts and spectral distribution at 5 GHz are in excellent agreement with those expected from surveys made at lower frequencies. There is no significant dependence of the spectral distribution on flux density in any of the surveys we have investigated, implying either a low redshift for the sources, or a systematic change in their properties with redshift.
