Abstract

Monitoring of 1–22 GHz spectra of blasars at the radio telescope RATAN-600 and their modeling using the known CATS data base are continued. The ‘‘Hedgehog’’ model proposed by N.S. Kardashev in 1969 and successfully applied later to explain variable spectra is used. For 13 objects modeled by relativistic proton jets, the main physical parameters were estimated. In 4 of them, new compact components in active nuclei may be detected. Accelerated protons may be high energy neutrino sources.
