“…This solution (a particular case of solutions in [24,25]) has a horizon at the largest real root r = r + of f (r). The horizon geometry is H 2 ×S d−4 , where the hyperboloid H 2 has coordinates (σ, φ).…”

We construct solutions for thin black rings in Anti-deSitter and deSitter spacetimes using approximate methods. Black rings in AdS exist with arbitrarily large radius and satisfy a bound |J| ≤ LM , which they saturate as their radius becomes infinitely large. For angular momentum near the maximum, they have larger area than rotating AdS black holes. Thin black rings also exist in deSitter space, with rotation velocities varying between zero and a maximum, and with a radius that is always strictly below the Hubble radius. Our general analysis allows us to include black Saturns as well, which we discuss briefly. We present a simple physical argument why supersymmetric AdS black rings must not be expected: they do not possess the necessary pressure to balance the AdS potential. We discuss the possible existence or absence of 'large AdS black rings' and their implications for a dual hydrodynamic description. An analysis of the physical properties of rotating AdS black holes is also included.

“…The solutions have a direct product structure of the extra S 1 with the base spacetime 1 . The extremal charged Kaluza-Klein black hole solutions with a twisted S 1 , space to higher-even-dimensional spaces are discussed in [56][57][58][59][60][61][62][63][64][65][66][67][68]. In this paper, we focus on the generalized Taub-NUT spaces in higher dimensions, which are not hyperkähler in general, as base spaces, and construct extremal charged solutions that have a twisted S 1 as an extra dimension explicitly.…”

We construct odd-dimensional extremal charged black hole solutions with a twisted S 1 as an extra dimension on generalized Euclidean Taub-NUT spaces. There exists a null hypersurface where an expansion for an outgoing null geodesic congruence vanishes, then these spacetimes look like black holes. We show that the metrics admit C 0 extension across the horizon, but some components of Riemann curvature diverge there if the dimension is higher than five. The singularity is relatively mild so that an observer along a free-fall geodesic can traverse the horizon. We also show solutions with a positive cosmological constant.

“…Furthermore in the same paper [8], Kraus et al have also suggested the counterterms for 4-and 5-dimensional asymptotically flat space-times with boundary R 2 × S 2 or R × S 3 and given a formula to calculate the conserved charges. In a recent work [9], Mann and Stelea have proposed a counterterm in 5-dimensional space-times with boundary topology R 2 ֒→ S 2 . This counterterm is equivalent to the counterterm of Kraus et al when the space-times have the boundary topology R 2 × S 2 .…”

Mass and thermodynamics of Kaluza–Klein black holes with squashed horizons

Recently a five-dimensional Kaluza-Klein black hole solution with squashed horizon has been found in hep-th/0510094. The black hole spacetime is asymptotically locally flat and has a spatial infinity S 1 ֒→ S 2 . By using "boundary counterterm" method and generalized Abbott-Deser method, we calculate the mass of this black hole. When an appropriate background is chosen, the generalized Abbott-Deser method gives the same mass as the "boundary counterterm" method. The mass is found to satisfy the first law of black hole thermodynamics. The thermodynamic properties of the Kaluza-Klein black hole are discussed and are compared to those of its undeformed counterpart, a five-dimensional Reissner-Nordström black hole.
