A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

Physics welcomes the idea that space contains energy whose gravitational effect
approximates that of Einstein's cosmological constant, Λ; today the concept is termed dark …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

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 …

The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

Abstract The spectroscopic Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) galaxy
sample represents the final set of galaxies observed using the original SDSS target …

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 …
