Research output: Contribution to conferenceAbstractAcademic


We present the first results from a systematic search for extragalactic substructure, using high resolution Adaptive Optics (AO) images of known strong gravitational lenses. In particular we focus on two lens systems, B0128+437 and B1939+666, placing limits on both luminous and dark matter substructure, and presenting additional science that is only obtainable through the use of AO.
