SEARCH FOR PROTON JETS IN BLASARS AS POSSIBLE EMITTERS OF HIGH-ENERGY NEUTRINOS
Abstract and keywords
Abstract (English):
We continue the RATAN-600 observations of instantaneous 1-22 GHz spectra of active galactic nuclei at 5-7 frequencies in 1997-2024. The main task is the analysis of the results including the CATS database for data beyond 1-22 GHz and the Hedgehog model proposed by N. S. Kardashev in 1969. The new goal is to study the physical parameters of jets in VLBI-blazars and search for compact bright strong variable proton jets as possible sources of high-energy neutrinos in proton-proton and proton-photon processes. Main results of estimating values for magnetic fields, brightness temperatures and angular sizes of both proton and electron jets in 9 blasars are presented. This allows to explain the RadioAstron extra-high brightness temperatures and magnetic fields as well as extremely compact cores in radio jets and to link proton sources of high-energy neutrinos with some radio jets.
