Scientific paper

Observations of the quasar 0836 + 710 at 1.7 GHz for 19 hr simultaneously with a 16-station VLBI array and the 7-station MERLIN array are reported. The bright and pronounced one-sided jet emerging from the core was mapped with 3 mas resolution over its total visible length of 130 mas at a dynamic range of 1000 to 1. It displays smooth bending, as well as a regular kink pattern, possibly due to magnetohydrodynamic instabilities. On larger scales, 0836 + 710 displays a diffuse secondary component aligned with the jet component located 1.3 arcsec from the core. No emission was found between the pc-scale structure and the diffuse component at a level of 1 mJy per beam, with a beam of 0.22 arcsec.
