High resolution radio interferometric observations of the radio target PKS show a bright, compact central source surrounded by several weaker discrete clumps of emission. These data are difficult to reconcile with the standard `core- jet' paradigm for active galaxies. Instead, modeling the radio image as a gravitational lens appears to provide a much better interpretation of the data. If true, PKS represents the smallest gravitational lens yet discovered. Furthermore, since it seems likely that the lensing object is a single galaxy, the mass distribution of PKS is simpler than many known lenses, and can be more accurately modeled, thus potentially providing a valuable determination of H_ o. The goal of this proposal is to confirm {or refute} the gravitational lens model for PKS through determination of the optical continuum morphology and redshift{s}. Since the total spatial extent of the radio emission associated with PKS is < 200 milliarcseconds, we propose to use t he high spatial resolution imaging capability of STIS imaging mode to determine the optical emission structure of PKSns, and then will followup with spectroscopic observations using STIS in low dispersion spectroscopy mode to measure the redshifts of the individual components of the putatively lensed background source.
