Bounds on M/R for static objects with a positive cosmological constant
Hakan Andreasson, Christian G. Boehmer
We consider spherically symmetric static solutions of the Einstein equations with a positive cosmological constant which are regular at the centre, and we investigate the infl…
On the steady states of the spherically symmetric Einstein-Vlasov system
Hakan Andreasson, Gerhard Rein
Using both numerical and analytical tools we study various features of static, spherically symmetric solutions of the Einstein-Vlasov system. In particular, we investigate the poss…
A numerical investigation of the stability of steady states and critical phenomena for the spherically symmetric Einstein-Vlasov system
Hakan Andreasson, Gerhard Rein
The stability features of steady states of the spherically symmetric Einstein-Vlasov system are investigated numerically. We find support for the conjecture by Zeldovich and Noviko…
Existence of CMC and constant areal time foliations in T^2 symmetric spacetimes with Vlasov matter
Hakan Andreasson, Alan D. Rendall, Marsha Weaver
The global structure of solutions of the Einstein equations coupled to the Vlasov equation is investigated in the presence of a two-dimensional symmetry group. It is shown that the…
