Several intriguing results were delivered by space and ground observations of 3C 273.
First, the shuttle movement of the apparent core at 7 mm was discovered. A self-referencing method was used to show that two independent regions in the jet of 3C 273 accelerated/decelerated simultaneously which can only be ascribed to the movement of the apparent core by 4.4 pc, deprojected, in 5 months. It was

Astrophysical jets are considered among the most powerful and variable known objects in the universe. VLBI observations provide us ultra-high resolution images which can reveal the innermost structural dynamics of the jet. This knowledge in a combination with the gamma-ray variability of a source gives us the unique opportunity to localize the gamma-ray emission as well as to estimate its distance

Synchrotron radiation from AGN jets can be linearly polarized up to ∼70% in
theory. However, the observed degree of linear polarization is usually much
lower. The weak linear polarization could to be due to (i) highly tangled
magnetic fields in turbulent plasma, (ii) strong Faraday rotation and (iii)
blending of polarized sub-components within the beam. The bright radio-galaxy

The high brightness temperatures, $T_\mathrm{b} \geq 10^{13}$ K, detected in several active galactic nuclei by RadioAstron space VLBI observations challenge theoretical limits. Refractive scattering by the interstellar medium may affect such measurements. We quantify the scattering properties and the sub-mas scale source parameters for the quasar B0529+483. Using RadioAstron correlated flux densit
