Symmetry-seeking spacetime coordinates
D. Garfinkle, C. Gundlach
In numerically constructing a spacetime that has an approximate timelike Killing vector, it is useful to choose spacetime coordinates adapted to the symmetry, so that the metric an…

Gauge-invariant and coordinate-independent perturbations of stellar collapse I: the interior
C. Gundlach, J. M. Martin-Garcia
Small non-spherical perturbations of a spherically symmetric but time-dependent background spacetime can be used to model situations of astrophysical interest, for example the prod…

Critical gravitational collapse of a perfect fluid: nonspherical perturbations
C. Gundlach
Continuously self-similar (CSS) solutions for the gravitational collapse of a spherically symmetric perfect fluid, with the equation of state p=kappa rho, with 0<kappa<1 a constant…
