Black Holes of D=5 Supergravity
We discuss some general features of black holes of five-dimensional supergravity, such as the first law of black hole mechanics. We also discuss some special features of rotating supersymmetric black holes. In particular, we show that the horizon is a non-singular, and non-rotating, null hypersurface whose intersection with a Cauchy surface is a squashed 3-sphere. We find the Killing spinors of...
متن کاملMulti - centered black holes in gauged D = 5 supergravity
One of the important consequences of the no-force condition for BPS states is the existence of stable static multi-center solutions, at least in ungauged supergravities. This observation has been at the heart of many developments in brane physics, including the construction of intersecting branes and reduced symmetry D-brane configurations corresponding to the Coulomb branch of the gauge theory...
متن کاملBlack Holes in Supergravity
A brief review is given of the use of duality symmetries to form orbits of supergravity black-hole solutions and their relation to extremal (i.e. BPS) solutions at the limits of such orbits. An important technique in this analysis uses a timelike dimensional reduction and exchanges the stationary black-hole problem for a nonlinear sigma-model problem. Families of BPS solutions are characterized...
متن کاملBlack Holes and Rings of minimal 5 - dim . Supergravity ∗
The aim of this talk is to address recent progress of 5-dimensional supergravity. We start with an issue related to the uniqueness theorem of black holes, which states that the most general 4-dim. black hole has to be of the Kerr-Newmann type, ie. is uniquely fixed by its conserved charges (mass, angular momentum, electric/magnetic charges) and the horizon topology is a 2-sphere [1, 2]. It impl...
متن کاملSymmetries of supergravity black holes
We investigate Killing tensors for various black hole solutions of supergravity theories. Rotating black holes of an ungauged theory, toroidally compactified heterotic supergravity, with NUT parameters and two U(1) gauge fields are constructed. If both charges are set equal, then the solutions simplify, and then there are concise expressions for rank-2 conformal Killing– Stäckel tensors. These ...
