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…

A transition from parabolic to conical shape as a common effect in nearby AGN jets
Y. Y. Kovalev, A. B. Pushkarev, E. E. Nokhrina +5
Observational studies of collimation in jets in active galactic nuclei (AGN) are a key to understanding their formation and acceleration processes. We have performed an automated s…

Inferring AGN jet parameters using Bayesian analysis of VLBI data with non-uniform jet model
Ilya N. Pashchenko, Alexander V. Plavin
Physical parameters of AGN jets observed with Very Long Baseline Interferometry (VLBI) are usually inferred from the core shift measurements or flux and size measured at a peak fre…
