Title:  Support theorem for universal compactified Jacobians

Abstract: We show that every direct summand appearing in the BBDG decomposition of the universal compactified Jacobians fiber map has full support on the base. As a corollary, the intersection cohomologies of the universal compactified Jacobians is independent to the degree d and stability condition \phi.
