Abstract
We clarify the higher-dimensional origin of a class of dyonic gaugings of supergravity recently discovered, when the gauge group is chosen to be ISO(7). This dyonically gauged maximal supergravity arises from consistent truncation of massive IIA supergravity on , and its magnetic coupling constant descends directly from the Romans mass. The critical points of the supergravity uplift to new four-dimensional anti–de Sitter space massive type IIA vacua. We identify the corresponding three-dimensional conformal field theory duals as super-Chern-Simons-matter theories with simple gauge group and level given by the Romans mass. In particular, we find a critical point that uplifts to the first explicit massive IIA background. We compute its free energy and that of the candidate dual Chern-Simons theory by localization to a solvable matrix model, and find perfect agreement. This provides the first precision match in massive type IIA string theory.
