    Dark Energy and the Accelerating Universe
    Joshua Frieman (Chicago/Fermilab), Michael Turner (Chicago), Dragan Huterer (Michigan)
    Invited review for Annual Reviews of Astronomy and Astrophysics; 53 pages, 18 figures
    (Submitted on 7 Mar 2008)

    "The discovery ten years ago 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% baryons, 20% dark matter, and 76% dark energy. At the same time, it posed one of the most profound mysteries in all of science, with deep connections to both astrophysics and particle physics. Cosmic acceleration could arise from the repulsive gravity of dark energy -- for example, the quantum energy of the vacuum -- or it may signal that General Relativity breaks down on cosmological scales and must be replaced. We review the present observational evidence for cosmic acceleration and what it has revealed about dark energy, discuss the various theoretical ideas that have been proposed to explain acceleration, and describe the key observational probes that will shed light on this enigma in the coming years."


    Michael Turner is one of the world's top cosmologists. This invited review probably sums up the current mainstream view of dark energy. A good point of reference.

    This paper puts the basic concepts of modern cosmology into perspective. I would call it a review paper, and a very good one. LCDM is a model that is affirmed on a daily basis on many fronts.
