Recent observations of Type 1a supernovae indicating an accelerating universe have once
more drawn attention to the possible existence, at the present epoch, of a small positive Λ …

This is a review of the physics and cosmology of the cosmological constant. Focusing on
recent developments, I present a pedagogical overview of cosmology in the presence of a …

We report measurements of the mass density, Ω $\mathstrut {_ {M}} $, and cosmological-
constant energy density, Ω $\mathstrut {_ {{\Lambda}}} $, of the universe based on the …

We measure cosmological parameters using the three-dimensional power spectrum P (k)
from over 200 000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with …

The cosmological constant ADS Classic is now deprecated. It will be completely retired in
October 2019. This page will automatically redirect to the new ADS interface at that point …

The application of Bayesian methods in cosmology and astrophysics has flourished over the
past decade, spurred by data sets of increasing size and complexity. In many respects …

Measurements of the distances to type Ia supernovae have produced strong evidence that
the expansion of the Universe is accelerating, implying the existence of a nearly uniform …

Distance measurements to type Ia supernovae (SNe Ia) indicate that the Universe is
accelerating and that two-thirds of the critical energy density exists in a dark-energy …

Dynamical systems theory is especially well-suited for determining the possible asymptotic
states (at both early and late times) of cosmological models, particularly when the governing …

In the near future, observations of the cosmic microwave background (CMB) anisotropies
will provide accurate determinations of many fundamental cosmological parameters. In this …
