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 …

We review different dark energy cosmologies. In particular, we present the Λ CDM
cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence …

ABSTRACT The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide
stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We …

A simple cosmological model with only six parameters (matter density, Ω mh 2, baryon
density, Ω bh 2, Hubble constant, H 0, amplitude of fluctuations, σ 8, optical depth, τ, and a …

We present the large-scale correlation function measured from a spectroscopic sample of
46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers …

We simulate the growth of galaxies and their central supermassive black holes by
implementing a suite of semi-analytic models on the output of the Millennium Run, a very …

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 …

We present distance measurements to 71 high redshift type Ia supernovae discovered
during the first year of the 5-year Supernova Legacy Survey (SNLS). These events were …

Dark energy, the mysterious cause of the accelerating expansion of the universe, is one of
the most important fields of research in astrophysics and cosmology today. Introducing the …

This paper focuses on cosmological constraints derived from analysis of WMAP data alone.
A simple ΛCDM cosmological model fits the five-year WMAP temperature and polarization …
