We present the spacetime of a five-dimensional static black hole within EinsteinMaxwell theory. The solution represents a Kaluza-Klein black hole, whereby the solution is wholly five-dimensional near the horizon, but becomes effectively fourdimensional (with a compact fifth dimension) at the spatial infinity. The black-hole is electrically charged and so has two horizons, with a horizon geometr...

The aim of this paper is to evaluate the energy distribution of some 2 + 1 black hole solutions applying the Landau-Lifshitz and Weinberg definitions. The metrics under consideration describe the charged black hole, the solution coupling to a static scalar field and the static and circularly symmetric exact solution of the Einstein-massless scalar equation. Further, we compare the expressions f...

We investigate how braneworld gravity affects gravitational collapse and black hole formation by studying Oppenheimer-Snyder-like collapse on a Randall-Sundrum type brane. Without making any assumptions about the bulk, we show that the exterior spacetime on the brane is non-static. In the special case where there is no matter but only collapsing Weyl " dark radiation " , a static black hole may...

With the development of string theory, black holes in higher-dimensional spacetimes have come to play a fundamental role in physics 1). Furthermore, the possibility of black hole production in high energy experiments has recently been suggested in the context of the so-called TeV gravity 2). A TeV-size black hole in TeV gravity is small enough to be well approximated by an asymptotically flat b...

We consider stationary extremal black hole solutions of the Einstein-Maxwell equations with a negative cosmological constant in four dimensions. We determine all non-static axisymmetric near-horizon geometries and all static near-horizon geometries for black holes of this kind. This allows us to deduce that the most general near-horizon geometry of an asymptotically globally AdS4 rotating extre...

In this work we study a gedanken experiment constructed in order to test the cosmic censorship hypothesis and the second law of black hole thermodynamics. Matter with a negative gravitating energy is imagined added to a near extremal U(1)-charged static black hole in Einstein-Maxwell theory. The dynamics of a similar process is studied and the thermo-dynamical properties of the resulting black ...

Static solutions of 5-dimensional gravity with two spatial Killing vectors are characterized by their rod structures. In this note we describe how the orbifold singularities and the topologies of the horizons and asymptotic regions can be determined from the corresponding rod diagrams. As an example we introduce the black lens, a static 5-dimensional black hole with a horizon of lens space topo...
