Non-Extremal Rotating Black Holes in Five-Dimensional Gauged Supergravity

Supersymmetric black holes in five-dimensional gauged supergravity must necessarily be rotating, and so in order to study the passage to black holes away from supersymmetry, it is of great interest to obtain non-extremal black holes that again have non-zero rotation. In this paper we find a simple framework for describing non-extremal rotating black holes in five-dimensional gauged supergravities. Using this framework, we are able to construct a new solution, describing the general single-charge solution of N = 2 gauged supergravity, with arbitrary values for the two rotation parameters. Previouslyobtained solutions with two or three equal charges also assume a much simpler form in the new framework, as also does the general solution with three unequal charges in ungauged N = 2 supergravity. We discuss the thermodynamics and BPS limit of the new single-charge solutions, and we discuss the separability of the Hamilton-Jacobi and Klein-Gordan equations in these backgrounds. 1 Research supported in part by DOE grant DE-FG03-95ER40917. 2 Research supported in part by DOE grant DE-FG02-95ER40893, NSF grant INTO3-24081, and the Fay R. and Eugene L.
