Episodic Self-Similarity in Critical Gravitational Collapse
J. Thornburg, Ch. Lechner, M. Purrer +2
We report on a new behavior found in numerical simulations of spherically symmetric gravitational collapse in self-gravitating SU(2) sigma models at intermediate gravitational coup…
SU(2) Cosmological Solitons
Christiane Lechner, Sascha Husa, Peter C. Aichelburg
We present a class of numerical solutions to the SU(2) nonlinear -model coupled to the Einstein equations with cosmological constant in spherical symmetry. These solut…
Type II Critical Collapse of a Self-Gravitating Nonlinear -Model
Sascha Husa, Christiane Lechner, Michael Pürrer +2
We report on the existence and phenomenology of type II critical collapse within the one-parameter family of SU(2) -models coupled to gravity. Numerical investigations in spheri…
