Current cosmological data indicate that our universe contains a substantial component of dark vacuum energy that is driving the cosmos to accelerate. We examine the immediate and longer term consequences of this dark energy (assumed here to have a constant density). Using analytic calculations and supporting numerical simulations, we present criteria for test bodies to remain bound to existing structures. We show that collapsed halos become spatially isolated and dynamically relax to a…

The optimal cosmic epoch for precision cosmology
The statistical uncertainty in measuring the primordial density perturbations on a given comoving scale is dictated by the number of independent regions of that scale that are accessible to an
The asymptotic form of cosmic structure : Small-scale power and accretion history
We explore the effects of small-scale structure on the formation and equilibrium of dark matter halos in a universe dominated by vacuum energy. We present the results of a suite of four N-body
The limits of bound structures in the accelerating Universe
According to the latest evidence, the Universe is entering an era of exponential expansion, where gravitationally bound structures will get disconnected from each other, forming isolated 'island
The ultimate halo mass in a ΛCDM universe
In the far future of an acceleratingCDM cosmology, the cosmic web of large-scale structure consists of a set of increasingly isolated haloes in dynamical equilibrium. We examine the ap- proach of
The Return of a Static Universe and the End of Cosmology
We demonstrate that as we extrapolate the current ΛCDM universe forward in time, all evidence of the Hubble expansion will disappear, so that observers in our “island universe” will be fundamentally
The return of a static universe and the end of cosmology
We demonstrate that as we extrapolate the current ΛCDM universe forward in time, all evidence of the Hubble expansion will disappear, so that observers in our “island universe” will be fundamentally
Dark Energy and the Accelerating Universe
Ten years ago, the discovery that the expansion of the universe is accelerating put in place the last major building block of the present cosmological model, in which the universe is composed of 4%
Redshift-space limits of bound structures
An exponentially expanding Universe, possibly governed by a cosmological constant, forces gravitationally bound structures to become more and more isolated, eventually becoming causally disconnected
Evolution of the cosmic microwave background
We discuss the time dependence and future of the cosmic microwave background (CMB) in the context of the standard cosmological model, in which we are now entering a state of endless accelerated


Long-term future of extragalactic astronomy
If the current energy density of the universe is indeed dominated by a cosmological constant, then high-redshift sources will remain visible to us only until they reach some finite age in their
Dark Energy and the Observable Universe
We consider ever-expanding big bang models with a cosmological constant, Λ, and investigate in detail the evolution of the observable part of the universe. We also discuss quintessence models from
Clusters, Cosmology and Mergers
The character of the galaxy cluster population holds clues to the identity of the particular world model that best describes our universe. Although clusters are complex in their fine detail, their
Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods that
Supernova limits on the cosmic equation of state
We use Type Ia supernovae studied by the High-z Supernova Search Team to constrain the properties of an energy component that may have contributed to accelerating the cosmic expansion. We find that
Cosmic Concordance and Quintessence
We present a comprehensive study of the observational constraints on spatially flat cosmological models containing a mixture of matter and quintessence—a time-varying, spatially inhomogeneous
Using the evolution of clusters to constrain Omega
The population of rich galaxy clusters evolves much more rapidly in a universe with critical density than one with low density, thus offering the possibility of determining the cosmological density
A Universal Density Profile from Hierarchical Clustering
We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have the same shape,
Cosmological constant and the fate of the DDM theory
We investigate the impact of the non-zero cosmological constant on the classical decaying dark matter theory developed by the late Dennis Sciama. In particular, we concentrate on the change in
