Abstract: Hierarchical clustering models of cold dark matter (CDM) predict that about 5% - 10% of a galaxy-sized halo with mass ∼ 1012 solar masses (M) resides in substructures (CDM subhalos) with masses ≤ 108M. To directly identify such substructures, we propose to observe radio continuum emission from multiply imaged QSOs using VSOP-2 with a high angular resolution.
