Bound states of spinning black holes in five dimensions

Understand

We find and study supergravity BPS bound states of five-dimensional spinning black holes in asymptotically flat spacetime.

• These solutions follow from multi-string solutions in six-dimensional minimal supergravity and can be uplifted to F-theory or M-theory.
• We analyze the regularity conditions and work out the example of a bound state of two black holes in detail.
• The bound state is supported by fluxes through nontrivial topologies exterior to the horizons and KK momentum.
