Microarcsecond structure of an AGN Jet via Interstellar Scintillation
  We have used the broadband backend available at the ATCA to study the fast
interstellar scintillation of quasar PKS 1257-326, resolving the core shift as
a function of frequency on scales less than 10 microarcseconds. In this short
paper we discuss the jet direction implied from the microarcsecond-scale core
shift in PKS 1257-326.
