Two physical characteristics of numerical apparent horizons
نویسنده
چکیده
This article translates some recent results on quasilocal horizons into the language of (3 + 1) general relativity so as to make them more useful to numerical relativists. In particular quantities are described which characterize how quickly an apparent horizon is evolving and how close it is to either equilibrium or extremality.

Black hole boundaries
Classical black holes and event horizons are highly non-local objects, defined in relation to the causal past of future null infinity. Alternative, quasilocal characterizations of black holes are often used in mathematical, quantum, and numerical relativity. These include apparent, killing, trapping, isolated, dynamical, and slowly evolving horizons. All of these are closely associated with two...
متن کاملHalf period theorem of binary black holes
Merging event horizons of the binary black holes will be investigated. Though recent development of the numerical study of the binary black hole coalescence has shown that their apparent horizons can orbit for many periods in the case of appropriate initial conditions, the apparent horizons only suggests the existence of an event horizon surrounding them. In the present article, we discuss how ...
متن کاملEvent horizons and apparent horizons in spherically symmetric geometries.
Spherical configurations that are very massive must be surrounded by apparent horizons. These in turn, when placed outside a collapsing body, have a fixed area and must propagate outward with a velocity equal to the velocity of radially outgoing photons. That proves, within the framework of the (1+3) formalism and without resorting to the Birkhoff theorem, that apparent horizons coincide with e...
متن کاملRevisiting Event Horizon Finders
Event horizons are the defining physical features of black hole spacetimes, and are of considerable interest in studying black hole dynamics. Here, we reconsider three techniques to localise event horizons in numerical spacetimes: integrating geodesics, integrating a surface, and integrating a levelset of surfaces over a volume. We implement the first two techniques and find that straightforwar...
متن کاملIntroduction to isolated horizons in numerical relativity
We present a coordinate-independent method for extracting the mass (M D) and angular momentum (JD) of a black hole in numerical simulations. This method, based on the isolated horizon framework, is applicable both at late times when the black hole has reached equilibrium, and at early times when the black holes are widely separated. Assuming that the spatial hypersurfaces used in a given numeri...
