Constraints on a quintessence model from gravitational lensing statistics.

SERENO M.

Abstract (from CDS):

Constraints on an exact quintessence scalar-field model with an exponential potential are derived from gravitational lens statistics. An exponential potential can account for data from both optical quasar surveys and radio-selected sources. Based on the Cosmic Lens All-Sky Survey (CLASS) sample, lensing statistics provides, for the pressureless matter density parameter, an estimate of ΩM0= 0.31+0.12–0.14.
