Scientific paper

We present the first sample of quasi-stellar objects (QSOs) behind the southern satellite galaxies of the Milky Way. These objects were sought for use as unresolved, inertial reference objects in proper motion studies of the Fornax, Carina and Sculptor dwarf spheroidal galaxies and the Small Magellanic Cloud (SMC). At least four new QSOs are presented behind each of the dwarf spheroidal galaxies and a further eight are presented behind the SMC. The majority of these QSOs have been identified as the optical counterparts to ROSAT X-ray sources. In the forthcoming 8-m telescope era, these objects may also represent useful probes of the interstellar media of these dwarf galaxies.
