Separating expansion from contraction: generalized TOV condition, LTB models with pressure and CDM
Morgan Le Delliou, Filipe C. Mena, José Pedro Mimoso
We discuss the existence of a dividing shell separating expanding and collapsing regions in spherically symmetric solutions with pressure. We obtain gauge invariant conditions rela…
Separating expansion from contraction in spherically symmetric models with a perfect-fluid: Generalization of the Tolman-Oppenheimer-Volkoff condition and application to models with a cosmological constant
José Pedro Mimoso, Morgan Le Delliou, Filipe C. Mena
We investigate spherically symmetric perfect-fluid spacetimes and discuss the existence and stability of a dividing shell separating expanding and collapsing regions. We perform a…
Formation of Higher-dimensional Topological Black Holes
Filipe C. Mena, Jose Natario, Paul Tod
We study higher dimensional gravitational collapse to topological black holes in two steps. Firstly, we construct some (n+2)-dimensional collapsing space-times, which include gener…
