Description
We study a new class of supersymmetric solutions in five-dimensional
supergravity representing multi-center 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 effect 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/Bena-Warner 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.
