Critical Phenomena in Gravitational Collapse
It was well known that strong enough initial configurations of matter field would result in gravitational collapse to black holes, whereas weak enough initial data become dispersed to infinity. However, what happens in the intermediate region was not clear until the discovery of the critical phenomena in gravitational collapse by Choptuik in 1993 [1]. He examined numerically the spacetime evolu...
متن کاملCritical Phenomena in Gravitational Collapse
As first discovered by Choptuik, the black hole threshold in the space of initial data for general relativity shows both surprising structure and surprising simplicity. Universality, power-law scaling of the black hole mass, and scale echoing have given rise to the term "critical phenomena". They are explained by the existence of exact solutions which are attractors within the black hole thresh...
متن کاملQuantum corrections to critical phenomena in gravitational collapse
We investigate conformally coupled quantum matter fields on spherically symmetric, continuously self-similar backgrounds. By exploiting the symmetry associated with the self-similarity the general structure of the renormalized quantum stress-energy tensor can be derived. As an immediate application we consider a combination of classical, and quantum perturbations about exactly critical collapse...
متن کاملOn critical behaviour in gravitational collapse
We give an approach to studying the critical behaviour that has been observed in numerical studies of gravitational collapse. These studies suggest, among other things, that black holes initially form with infinitesimal mass. We show generally how a black hole mass formula can be extracted from a transcendental equation. Using our approach, we give an explicit one parameter set of metrics that ...
متن کاملCritical phenomena and self-similarity in the gravitational collapse of radiation fluid.
We observe critical phenomena in spherical collapse of radiation fluid. A sequence of spacetimes S[η] is numerically computed, containing models (η ≪ 1) that adiabatically disperse and models (η ≫ 1) that form a black hole. Near the critical point (ηc), evolutions develop a self-similar region within which collapse is balanced by a strong, inward-moving rarefaction wave that holds m(r)/r consta...
