Content
The quasar 3C279 is very well known for its high luminosity, polarization, and variability, has been widely studied and monitored. Recently, the space-VLBI mission RadioAstron revealed a filamentary structure in the jet of this source, offering unprecedented insights into its innermost region. Building on these findings, new data were analyzed four years later at 22 GHz (K-band) using the same mission RadioAstron along with 14 ground-based stations, including several from the European VLBI Network (EVN), and achieving a resolution of almost 15 microarcseconds.
The new results shed some light on the temporal evolution of the jet's structure, with notable changes in its filamentary features and polarization properties, further broadening our understanding of this fascinating and complex source.
