Abstract

VLBI enables us to observe synchrotron radiation from relativistic electrons in the innermost regions of blazars. According to the leptonic models, the same electrons pro- duce also the high-energy radiation component through inverse Compton scattering of seed photons. One demon- stration of the connection between high- and low-energy emission is the correlation found between VLBI compo- nent ejections and gamma-ray flares. VLBI can probe the physical parameters of emitting re- gions, like Lorentz factors and magnetic field direction, and can improve SED modeling by providing the spectra of individual jet components.
