Kaluza-Klein Black Holes with Squashed Horizons
Abstract
We study geometrical structures of charged static black holes in the five-dimensional Einstein-Maxwell theory. The black hole has horizons in the shape of squashed S^3, and its asymptotic structure is a twisted S^1 bundle over the four-dimensional flat spacetime at spatial infinity. The spacetime that looks like a five-dimensional black hole in the vicinity of the hole gives an effective four-dimensional black hole with a compact extra dimension at infinity.Keywords
