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…
Black Holes and Galactic Density Cusps : From Black Hole to Bulge
Morgan Le Delliou, Richard N. Henriksen, Joseph D. Macmillan
Aims. In this paper we continue our study of density cusps that may contain central black holes. Methods. We recall our attempts to use distribution functions with a memory of self…
Black Holes and Galactic Density Cusps Spherically Symmetric Anisotropic Cusps
Morgan Le Delliou, Richard N. Henriksen, Joseph D. Macmillan
Aims: In this paper we study density cusps that may contain central black holes. The actual co-eval self-similar growth would not distinguish between the central object and the sur…
Black holes and Galactic density cusps -- I. Radial orbit cusps and bulges
Morgan Le Delliou, Richard N. Henriksen, Joseph D. Macmillan
In this paper, we study the distribution functions that arise naturally during self-similar radial infall of collisionless matter. Such matter may be thought of either as stars or…
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…
Separating expansion from contraction and generalizing TOV condition in spherically symmetric models with pressure
Morgan Le Delliou, José Pedro Mimoso
We investigate spherically symmetric solutions with pressure and discuss the existence of a dividing shell separating expanding and collapsing regions. We perform a 3+1 splitting a…
