2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/1956We present wide-field images of the quadruple gravitational lenses B1422+231 and MGJ0414+0534 obtained from global Very Long Baseline Interferometry (VLBI) observations at 8.4 GHz on 23 November 1997. We present also a lens model for MGJ0414+0534, which reproduces the core positions and flux densities of the VLBI images, combining a singular isothermal ellipsoid with external shear, and a singular isothermal sphere to represent, respectively, the main lens galaxy and its neighbor, a faint galaxy near one of the images.Proceedings of the 4th Scientific Meeting of the Spanish Astronomical Society, Zamorano J., Gorgas J., Gallego J.
