VLBI monitoring reveals a 21c apparent speed in TXS 0506+056, interpreted as evidence for a stratified jet with Gamma>20 spine that accounts for neutrino production and radio flare timing.
Efficient neutrino production in blazar jets requires an external radiation field that strongly dominates the magnetic field (Y>>1), which radio constraints place near the broad-line region and only for uncommon jet acceleration or beaming conditions.
VLBI observations resolve NGC 7479's nucleus into two radio components separated by ~30 mas with an apparent change in separation over a decade, suggesting relativistic jet motion or nuclear wind shocks.
SKA-VLBI can deliver high-sensitivity milliarcsecond imaging and polarimetry of faint blazars to constrain models of high-energy photon and neutrino emission in AGN jets.
