In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

Over the past decade, f (R) theories have been extensively studied as one of the simplest
modifications to General Relativity. In this article we review various applications of f (R) …

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 …

ABSTRACT WMAP precision data enable accurate testing of cosmological models. We find
that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a …

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 …

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

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 …

Abstract We have discovered 16 Type Ia supernovae (SNe Ia) with the Hubble Space
Telescope (HST) and have used them to provide the first conclusive evidence for cosmic …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …
