  • Abstract We observed the quadruple gravitational lens MG J0414+0534 on 23 November 1997 with a global VLBI array at 8.4 GHz. We report wide-field imaging results of the gravitational lens components at submilliarcsecond resolution, displaying complex core-like and jet-licke extended structures. A simple model combining a primary ingular isothermal ellipsoid to represent the main lens galaxy, external shear, and a singular isothermal sphere to represent nearby object X accouns well for the core positions and flux densities of the VLBI images. This model predicts delays between the different lensed images from days to weeks.
