Comment on ``Strength and genericity of singularities in Tolman-Bondi-de Sitter collapse'' and a note on central singularities
Brien C. Nolan, Filipe C. Mena, Sergio M. C. V. Goncalves
It has been claimed that the Lemaitre-Tolman-Bondi-de Sitter solution always admits future-pointing radial time-like geodesics emerging from the shell-focussing singularity, regard…
Non-radial null geodesics in spherical dust collapse
Filipe C Mena, Brien C Nolan
The issue of the local visibility of the shell-focussing singularity in marginally bound spherical dust collapse is considered from the point of view of the existence of future-dir…
Cosmic no-hair: non-linear asymptotic stability of de Sitter universe
Marco Bruni, Filipe C. Mena, Reza Tavakol
We study the asymptotic stability of de Sitter spacetime with respect to non-linear perturbations, by considering second order perturbations of a flat Robertson-Walker universe wit…
