Quasilocal energy for a Kerr black hole.
The quasilocal energy associated with a constant stationary time slice of the Kerr spacetime is presented. The calculations are based on a recent proposal [1] in which quasilocal energy is derived from the Hamiltonian of spatially bounded gravitational systems. Three different classes of boundary surfaces for the Kerr slice are considered (constant radius surfaces, round spheres, and the ergosu...
متن کاملBoosted Kerr black hole
Initial data for boosted Kerr black hole are constructed in an axially symmetric case. Momentum and hamiltonian constraints are solved numerically using finite element method (FEM) algorithms. Both BowenYork and puncture boundary conditions are adopted and appropriate results are compared. Past and future apparent horizons are also found numerically and the Penrose inequality is tested in detai...
متن کاملRevised upper limit to energy extraction from a Kerr black hole.
We present a new upper limit on the energy that may be extracted from a Kerr black hole by means of particle collisions in the ergosphere (i.e., the "collisional Penrose process"). Earlier work on this subject has focused largely on particles with critical values of angular momentum falling into an extremal Kerr black hole from infinity and colliding just outside the horizon. While these collis...
متن کاملEnergy Extraction from a Kerr Black Hole - An Ultimate Power Source in the Universe?
It is widely believed that some classes of high-energy transients may be powered by the rotational energy of a rapidly spinning black hole. The energy extraction mechanism commonly discussed involves macroscopic magnetic fields that are produced by currents flowing in a disk or torus surrounding the black hole. The discovery of relativistic jets in radio loud AGNs nearly half a century ago was ...
متن کاملA Local Energy Estimate on Kerr Black Hole Backgrounds
We study dispersive properties for the wave equation in the Kerr spacetime with small angular momentum. The main result of this paper is to establish uniform energy bounds and local energy decay for such backgrounds. This follows similar results for the Schwarzschild space-time proved earlier in [4], [9] and [12] and extended in earlier work [32] of the authors and collaborators.
