Studies of sources from the WMAP catalog. Vol'vach A.E., Vol'vach L.N., Kardashev N.S., Larionov M.G. <Astron. Zh. 85, 483 (2008)> =2008AZh....85..483V =2008ARep...52..429V
ADC_Keywords: Radio sources Abstract: Observations of a complete sample of sources from the WMAP catalog were obtained at 22.2 and 36.8GHz on the RT-22 radio telescope of the Crimean Astrophysical Observatory. We have determined the distribution of the source spectral indices between these frequencies. The distributions of the spectral indices of the WMAP catalog (between 23 and 33GHz) and in the RT-22 sample have the same shape and half-width, suggesting that the mean source parameters are constant in time. We have plotted the logN-logS dependence down to the flux levels of about 0.1Jy using pilot data from the AT20 survey, where a cosmological "cutoff" in the source counts is already observed. The variability of individual sources in connection with flare activity is considered. The optical characteristics of the complete sample of WMAP sources are compared to those of identified AT20 survey sources. Description: The observational data were obtained on the 22-meter RT-22 radio telescope of the Crimean Astrophysical Observatory at 22.2 and 36.8GHz. File Summary:
