Abstract: Hierarchical clustering models of cold dark matter CDM predict that about5% - 10% of a galaxy-sized halo with mass ~ 10^12 solar masses M sun residesin substructures CDM subhalos with masses <= 10^8 M sun. To directly identifysuch substructures, we propose to observe radio continuum emission frommultiply imaged QSOs using VSOP-2 with a high angular resolution.
