Abstract
Radio continuum surveys have, in the past, been of restricted use incosmology. Most studies have concentrated on cross-correlations with the cosmicmicrowave background to detect the integrated Sachs-Wolfe effect, due to thelarge sky areas that can be surveyed. As we move into the SKA era, radiocontinuum surveys will have sufficient source density and sky area to play amajor role in cosmology on the largest scales. In this chapter we summarise theexperiments that can be carried out with the SKA as it is built up through thecoming decade. We show that the SKA can play a unique role in constraining thenon-Gaussianity parameter to \sigma(f_NL) ~ 1, and provide a unique handle onthe systematics that inhibit weak lensing surveys. The SKA will also providethe necessary data to test the isotropy of the Universe at redshifts of orderunity and thus evaluate the robustness of the cosmological principle.Thus, SKAcontinuum surveys will turn radio observations into a central probe ofcosmological research in the coming decades.
