Left: optical r′-band GMOS-S image of PKS 1814-637 obtained from the Gemini South. The bright peak coincides with a foreground star. Despite the presence of the star, the extended disky component and dust-lane structure in the galaxy are clearly visible. Right: composite radio map showing the 2.3 GHz VLBI image (Tzioumis et al. 2002) with the 8.4 GHz (i.e. high resolution) image from Ojha et al. 2004) superimposed. This overlay illustrates the presence of a compact component (SE of the brighter lobe) that becomes prominent in the high frequency observations: we identify this component with the radio core. The image at 2.3 GHz was obtained from the SHEVE array, the peak a level is 1.7 Jy and contours are shown at –1.5, 1.5, 3, 6, 12, 18, 35, 50, 65, 80% of the peak (from Tzioumis et al. 2002).
