DARK ENERGY AND THE STATISTICAL STUDY OF THE OBSERVED IMAGE SEPARATIONS OF THE MULTIPLY-IMAGED SYSTEMS IN THE CLASS STATISTICAL SAMPLE
2004
International Journal of Modern Physics D
The present day observations favour a universe which is flat, accelerated and composed of ∼ 1/3 matter (baryonic + dark) and ∼ 2/3 of a negative pressure component, usually referred to as dark energy or quintessence. The Cosmic Lens All Sky Survey (CLASS), the largest radio-selected galactic mass scale gravitational lens search project to date, has resulted in the largest sample suitable for statistical analyses. In the work presented here, we exploit observed image separations of the multiply
