Future evolution of cosmic structure in an accelerating universe

摘要: Current cosmological data indicate that our universe contains a substantial component of dark vacuum energy is driving the cosmos to accelerate. We examine immediate and longer term consequences this (assumed here have constant density). Using analytic calculations supporting numerical simulations, we present criteria for test bodies remain bound existing structures. show collapsed halos become spatially isolated dynamically relax particular density profile with logarithmic slope steeper than -3 at radii beyond r200. The asymptotic form spacetime metric then specified. develop scenario further by determining effects accelerating expansion on background radiation fields individual particles. In an appendix, generalize these results include quintessence.
