Critical collapse of a spherically symmetric ultrarelativistic fluid in $2 + 1$ dimensions

Patrick Bourg, Carsten Gundlach

We carry out numerical simulations of the gravitational collapse of a perfect fluid with the ultrarelativistic equation of state $P = κ ρ$ , in spherical symmetry in $2 + 1$ spacetime di…

Fully constrained, high-resolution shock-capturing, formulation of the Einstein-fluid equations in $2 + 1$ dimensions

Carsten Gundlach, Patrick Bourg, Alex Davey

Four components of the axisymmetric Einstein equations in 2+1 dimensions with negative cosmological constant can be written as $\nabla_{a} M = \dots$ and $\nabla_{a} J = \dots$ , where the do…

Rigidly rotating perfect fluid stars in $2 + 1$ dimensions

Carsten Gundlach, Patrick Bourg

Cataldo has found all rigidly rotating self-gravitating perfect fluid solutions in 2+1 dimensions with a negative cosmological constant $Λ$ , for a density that is specified a prior…
