چکیده

A bstract We find a new non BPS solution in N = 2 D 4 gauged supergravity coupled to U(1) gauge fields and matter. It consists closed universe with two extremal black holes of equal size, surrounding singularities. They have opposite magnetic charges (and no electric charges), but stay static equilibrium thanks the positive pressure cosmological constant. The geometry is perfectly symmetric under exchange flip sign charges. However scalar field constant symmetric, different values at horizons, which depend on real modulus. Remarkably we show that it satisfies attractor mechanism entropy indeed depends only At one horizons becomes $$ \frac{1}{2} 1 2 -BPS supersymmetric, while other there supersymmetry, remains independent from

Black hole in de Sitter space

If cosmological constant is positive, a black hole is naturally described by the Schwarzschild-de Sitter solution with two horizons. We use the global method to extract the topological information and the selection rule for the Gibbons-Hawking temperature for the thermal vacua. These are related to the Euler number of the Euclidean section whose topology is more complicated than expected. We al...

A black hole hologram in de Sitter space

In this paper we show that the entropy of de Sitter space with a black hole in arbitrary dimension can be understood using a modified Cardy-Verlinde entropy formula. We also comment on the observer dependence of the de Sitter entropy and make a conjecture about the form of the conformal anomaly in arbitrary dimension.

Do supersymmetric anti-de Sitter black rings exist?

We determine the most general near-horizon geometry of a supersymmetric, asymptotically anti-de Sitter, black hole solution of five-dimensional minimal gauged supergravity that admits two rotational symmetries. The near-horizon geometry is that of the supersymmetric, topologically spherical, black hole solution of Chong et al. This proves that regular supersymmetric anti-de Sitter black rings w...

Hawking radiation of Kerr-Newman-de Sitter black hole

We extend the classical Damour-Ruffini method and discuss Hawking radiation in KerrNewman-de Sitter(KNdS) black hole. Under the condition that the total energy, angular momentum and charge of spacetime are conserved, taking the reaction of the radiation of the particle to the spacetime and the relation between the black hole event horizon and the cosmological horizon into consideration, we deri...

Conformal isometry of the Reissner-Nordström-de Sitter black hole

It was pointed out by Couch and Torrence that the extreme Reissner-Nordström solution possesses a discrete conformal isometry. Using results of Romans, it is shown that such a symmetry also exists when a non-zero cosmological constant is allowed. Introduction In [1], Couch and Torrence found a conformal isometry that interchanges the event horizon and null infinity J of an extremal Reissner-Nor...
