The cosmological constant and dark energy

PJE Peebles, B Ratra - Reviews of modern physics, 2003 - APS
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 …

The physics of microwave background anisotropies
