Constraints on scalar-field dark energy from the Cosmic Lens All-Sky Survey gravitational lens statistics.

CHAE K.-H., CHEN G., RATRA B. and LEE D.-W.

Abstract (from CDS):

We use the statistics of strong gravitational lensing based on Cosmic Lens All-Sky Survey (CLASS) data to constrain cosmological parameters in a spatially flat, inverse power-law potential energy density scalar-field dark energy cosmological model. The lensing-based constraints are consistent with, but weaker than, those derived from Type Ia supernova redshift-magnitude data, and mildly favor the Einstein cosmological constant limit of this dark energy model.
