Einstein-matter dynamics with a hyperboloidal evolution code — •Oliver Rinne — Albert-Einstein-Institut, Potsdam

In hyperboloidal evolution, spacetime is foliated by spacelike hypersurfaces approaching future null infinity, thereby avoiding any problems arising from an artificial timelike boundary. With V. Moncrief we developed a conformal constrained 3+1 formulation of the Einstein equations on such a foliation. In this talk I will present some new numerical results on evolutions of Yang-Mills and/or massive scalar fields coupled to the Einstein equations, focusing on the dynamical role played by nontrivial static solutions.
