The science impact of high sensitivity VLBI with SKA
The Square Kilometre Array (SKA), with the aim of achieving a collecting area of one square kilometre, will be the world’s largest radio telescope. A scientific collaboration between 12 coun- tries (with more to join), it will consist of one Observatory with 2 telescopes located in South Africa and Australia. The telescope deployment is planned in two phases, but even in its first stage (SKA1) it will already enable transformational science in a broad range of scientific objec- tives. The inclusion of SKA1 in the Global VLBI networks (SKA-VLBI) will provide access to very high angular resolution to SKA science programmes in anticipation of the science to be re- alized with the full telescope deployment (SKA2). This contribution provides an overview of the SKA Observatory VLBI capability, the key operational concepts and outlines the need to update the science use cases.
