Directional association of TeV to PeV astrophysical neutrinos with radio blazars
A. V. Plavin, Y. Y. Kovalev, Y. A. Kovalev +1
Recently we have shown that high-energy neutrinos above 200 TeV detected by IceCube are produced within several parsecs in the central regions of radio-bright blazars, that is acti…
Optical polarization properties of AGN with significant VLBI-Gaia offsets
Y. Y. Kovalev, D. I. Zobnina, A. V. Plavin +1
Significant positional offsets of the value from 1 mas to more than 10 mas were found previously between radio (VLBI) and optical (Gaia) positions of active galactic nuclei (AGN).…
Observational evidence for the origin of high-energy neutrinos in parsec-scale nuclei of radio-bright active galaxies
A. V. Plavin, Y. Y. Kovalev, Y. A. Kovalev +1
Observational information on high-energy astrophysical neutrinos is being continuously collected by the IceCube observatory. However, the sources of neutrinos are still unknown. In…
