Title: Topological stars

Abstract: In this talk, I will discuss a class of smooth spherically symmetric solutions in five dimensional Einstein-Maxwell theory that look like black holes upon a Kaluza-Klein reduction to four dimensions. These are simple prototypes of black hole microstate geometries that can be macroscopically large compare to the Kaluza-Klein circle. The smooth five dimensional space time contains topological cycles that are stabilized by magnetic flux. These topological cycle can also be placed behind black string horizons where they smooth out curvature singularities.
