The first space VLBI image of 3C279

The first 5 GHz VSOP (VLBI Space Observatory Programme) observation of the quasar 3C279 was conducted on 10 January 1998 with the satellite HALCA and an array of ground radio telescopes. The high dynamic range image presented here reveals that the core and the secondary component ∼3 milli-arcseconds from the core dominate the compact radio emission, but that lower level features at intermediate distances from the core are also evident. © 2000 COSPAR.
