A cosmological constant limits the size of black holes.

In a space-time with cosmological constant Λ > 0 and matter satisfying the dominant energy condition, the area of a black or white hole cannot exceed 4π/Λ. This applies to event horizons where defined, i.e. in an asymptotically deSitter space-time, and to outer trapping horizons (cf. apparent horizons) in any space-time. The bound is attained if and only if the horizon is identical to that of t...

Thermal Decay of the Cosmological Constant into Black Holes

We show that the cosmological constant may be reduced by thermal production of membranes by the cosmological horizon, analogous to a particle “going over the top of the potential barrier”, rather than tunneling through it. The membranes are endowed with charge associated with the gauge invariance of an antisymmetric gauge potential. In this new process, the membrane collapses into a black hole,...

Black holes in Gödel-type universes with a cosmological constant

We discuss supersymmetric black holes embedded in a Gödel-type universe with cosmological constant in five dimensions. The spacetime is a fibration over a four-dimensional Kähler base manifold, and generically has closed timelike curves. Asymptotically the space approaches a deformation of AdS5, which suggests that the appearance of closed timelike curves should have an interpretation in some d...

Rotating black holes in higher dimensions with a cosmological constant.

We present the metric for a rotating black hole with a cosmological constant and with arbitrary angular momenta in all higher dimensions. The metric is given in both Kerr-Schild and the Boyer-Lindquist form. In the Euclidean-signature case, we also obtain smooth compact Einstein spaces on associated S(D-2) bundles over S2, infinitely many for each odd D>/=5. Applications to string theory and M-...

Charged dilaton black holes with a cosmological constant.

The properties of static spherically symmetric black holes, which are either electrically or magnetically charged, and which are coupled to the dilaton in the presence of a cosmological constant, Λ, are considered. It is shown that such solutions do not exist if Λ > 0 (in arbitrary spacetime dimension ≥ 4). However, asymptotically anti-de Sitter black hole solutions with a single horizon do exi...
