ABSTRACT  |  We study a new class of supersymmetric solutions in five-dimensional supergravity representing multicenter configurations of codimension-2 branes along arbitrary curves. Codimension-2 branes are produced in generic situations out of ordinary branes of higher codimension by the supertube transition and, when they are exotic branes, spacetime generally becomes non-geometric. The solutions are characterized by a set of harmonic functions on R^3 with non-trivial monodromies around codimension- 2 branch-point singularities. The solutions can be regarded as generalizations of the Bates-Denef/BenaWarner multi-center solutions with codimension-3 centers to include codimension-2 ones. We present some explicit examples of solutions with codimension-2 centers, and discuss their relevance for the black microstate (non-)geometry program.
