Dim cores of radio-bright AGN jets: VLBI and Gaia astrometry pinpoint different parsec-scale features
A. V. Popkov, Y. Y. Kovalev, A. V. Plavin +2
Astrometry with the very long baseline radio interferometry (VLBI) allows to determine the position of a point close to the source's brightest compact detail at milliarcsecond scal…
