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…
Cosmology from gravitational lens time delays and Planck data
S. H. Suyu, T. Treu, S. Hilbert +11
Under the assumption of a flat Lambda-CDM cosmology, recent data from the Planck satellite point toward a Hubble constant that is in tension with that measured by gravitational len…
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…
