Numerical construction of initial data sets of binary black hole type using a parabolic-hyperbolic formulation of the vacuum constraint equations
Florian Beyer, Leon Escobar, Jörg Frauendiener +1
In this paper we investigate the parabolic-hyperbolic formulation of the vacuum constraint equations introduced by R{á}cz with a view to constructing multiple black hole initial da…
Asymptotics of solutions of a hyperbolic formulation of the constraint equations
Florian Beyer, Leon Escobar, Jörg Frauendiener
In this paper we consider the hyperbolic formulation of the constraints introduced by Rácz. Using the numerical framework recently developed by us we construct initial data sets wh…
Criticality of inhomogeneous Nariai-like cosmological models
Florian Beyer, Leon Escobar, Jörg Frauendiener
In this paper, we construct and study solutions of Einstein's equations in vacuum with a positive cosmological constant which can be considered as inhomogeneous generalizations of…
Numerical solutions of Einstein's equations for cosmological spacetimes with spatial topology S3 and symmetry group U(1)
Florian Beyer, Leon Escobar, Jörg Frauendiener
In this paper we consider the single patch pseudo-spectral scheme for tensorial and spinorial evolution problems on the 2-sphere presented in [3,4] which is based on the spin-weigh…
Graceful exit from inflation for minimally coupled Bianchi A scalar field models
Florian Beyer, Leon Escobar
We consider the dynamics of Bianchi A scalar field models which undergo inflation. The main question is under which conditions does inflation come to an end and is succeeded by a d…
Holographic dark energy with non-minimal coupling
L. N. Granda, L. D. Escobar
We study a scalar field non-minimally coupled to the curvature, in the framework of holographic dark energy. We obtain a relation between the coupling of the scalar field and the h…
