Two black hole initial data
In [1] Misner proposed two-body wormhole initial data and in [2] he used the method of images to describe the time-symmetric initial data for an arbitrary number N of particles (see also [3] for a review of time-symmetric initial data). Such data may be viewed as a collection of Einstein-Rosen bridges connecting two isometric sheets. If we restrict ourselves to just one of them, we can view suc...
متن کاملInitial data for black hole collisions
The physical system we want to describe is a binary system of two black holes. It is expected that lot of such systems exist in the universe. Moreover, these systems are expected to have the following two properties. First, gravitational radiation will be emitted by them and the new detectors will be able to measure it. Second, these systems are completed described by the Einstein field equatio...
متن کاملImproved initial data for black hole collisions
Numerical relativity codes now being developed will evolve initial data representing colliding black holes at a relatively late stage in the collision. The choice of initial data used for code development has been made on the basis of mathematical definitiveness and usefulness for computational implementation. By using the “particle limit” (the limit of an extreme ratio of masses of colliding h...
متن کاملEmbedding initial data for black hole collisions
The visualization of curved sections of spacetime can be of considerable conceptual value. We discuss here the visualization of initial data for the problem of the head-on collision of two black holes. The problem of constructing the embedding diagram is explicitly presented for the best studied initial data, the Misner geometry. We present a partial solution of the embedding diagrams and discu...
متن کاملUnderstanding initial data for black hole collisions
Numerical relativity, applied to collisions of black holes, starts with initial data for black holes already in each other’s strong field. For the initial data to be astrophysically meaningful, it must approximately represent conditions that evolved from holes originally at large separation. The initial hypersurface data typically used for computation is based on mathematically simplifying pres...
