Constraints on cosmological models from strong gravitational lensing systems

Cao, Shuo; Biesiada, Marek; Zhu, Zong-Hong +2 more

Strong lensing has developed into an important astrophysical tool for probing both cosmology and galaxies (their structure, formation, and evolution). Using the gravitational lensing theory and cluster mass distribution model, we try to collect a relatively complete observational data concerning the Hubble constant independent ratio between two an…

The rates and time-delay distribution of multiply imaged supernovae behind lensing clusters

Richard, Johan; Hjorth, Jens; Li, Xue

Time delays of gravitationally lensed sources can be used to constrain the mass model of a deflector and determine cosmological parameters. We here present an analysis of the time-delay distribution of multiply imaged sources behind 17 strong lensing galaxy clusters with well-calibrated mass models. We find that for time delays less than 1000 days…
