Improved 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 کاملBlack Hole Binaries
4.1.1 Scope of this review We focus on 18 black holes with measured masses that are located in X–ray binary systems. These black holes are the most visible representatives of an estimated ∼300 million stellar–mass black holes that are believed to exist in the Galaxy (van den Heuvel 1992; Brown & Bethe 1994; Timmes et al. 1996; Agol et al. 2002). Thus the mass of this particular form of dark mat...
متن کاملTwo 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 کاملInventory of Black Hole Binaries
A small group of X-ray binaries currently provides the best evidence for the existence of stellar-mass black holes. These objects are interacting binary systems where the X-rays arise from accretion of material onto a compact object (i.e. an object with a radius of less than a few hundred km). In some favourable cases, optical studies of the companion star lead to dynamical mass estimates for b...
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...
