Dark energy with gravitational lens time delays
T. Treu, P. J. Marshall, F. -Y. Cyr-Racine +35
Strong lensing gravitational time delays are a powerful and cost effective probe of dark energy. Recent studies have shown that a single lens can provide a distance measurement wit…
Reconstructing the Lensing Mass in the Universe from Photometric Catalogue Data
Thomas E. Collett, Philip J. Marshall, Matthew W. Auger +8
High precision cosmological distance measurements towards individual objects such as time delay gravitational lenses or type Ia supernovae are affected by weak lensing perturbation…
Improving the precision of time-delay cosmography with observations of galaxies along the line of sight
Zach S. Greene, Sherry H. Suyu, Tommaso Treu +8
In order to use strong gravitational lens time delays to measure precise and accurate cosmological parameters the effects of mass along the line of sight must be taken into account…
