Description

General-relativistic cosmological models where vacuum interacts with cold dark matter (iV-CDM models) maybe a good alternative to the standard LCDM scenario. The post-Friedmann approximation generalises to cosmology post-Newtonian methods and we have used it to extract frame-dragging, a pure GR effect, from standard N-body simulations in LCDM and in f(R) models. After briefly summarising the iVCDM scenario and the post-Friedmann approximation I will discuss its extension from LCDM to the iVCDM case, concluding with an outlook on future work.
