SKA-VLBI Key Science Programmes

A significant fraction of the observing time with the two phase-I SKA telescopes (SKA1-LOW & SKA1-MID) will be spent on Key Science Projects led by member country scientists. The various SKA Science Working Groups, including the VLBI Focus Group are in the process of defining KSPs that are aligned with the High Priority Science Objectives of the SKA. At the moment it is not clear how the special observing mode of SKA-VLBI - when the SKA1 components are phased-up and included in VLBI networks - could be incorporated in KSPs. The VLBI community needs to be prepared by the time the KSP proposal calls are expected (mid-2020s). In this paper we outline the basic concept of SKA-VLBI, and some possibilities for us to engage in SKA KSPs.
