Critical phenomena in gravitational collapse (Physics Reports)
Carsten Gundlach
In general relativity black holes can be formed from regular initial data that do not contain a black hole already. The space of regular initial data for general relativity therefo…
Spacetime structure of self-similar spherically symmetric perfect fluid solutions
B. J. Carr, Carsten Gundlach
We classify all spherically symmetric and homothetic spacetimes that are allowed kinematically by constructing them from a small number of building blocks. We then restrict attenti…
Black-hole threshold solutions in stiff fluid collapse
Patrick R. Brady, Matthew W. Choptuik, Carsten Gundlach +1
Numerical studies of the gravitational collapse of a stiff (P=rho) fluid have found the now familiar critical phenomena, namely scaling of the black hole mass with a critical expon…
Perturbations of an exact solution for 2+1 dimensional critical collapse
David Garfinkle, Carsten Gundlach
We find the perturbation spectrum of a family of spherically symmetric and continuously self-similar (CSS) exact solutions that appear to be relevant for the critical collapse of s…
