Clusters of galaxies are the most recently assembled, massive, bound structures in the
Universe. As predicted by General Relativity, given their masses, clusters strongly deform …

▪ Abstract Gravitational lenses can provide crucial information on the geometry of the
Universe, on the cosmological scenario of formation of its structures as well as on the history …

We present results from a comprehensive lensing analysis in Hubble Space Telescope
(HST) data of the complete Cluster Lensing And Supernova survey with Hubble cluster …

In this paper, we describe a procedure for modelling strong lensing galaxy clusters with
parametric methods, and to rank models quantitatively using the Bayesian evidence. We use …

We present a new determination of the concentration–mass (c–M) relation for galaxy
clusters based on our comprehensive lensing analysis of 19 X-ray selected galaxy clusters …

Deflection of light by gravity was predicted by General Relativity and observationally
confirmed in 1919. In the following decades, various aspects of the gravitational lens effect …

We present a determination of the Hubble constant from the joint, free-form analysis of eight
strongly, quadruply lensing systems. In the concordance cosmology, we find with a precision …

We describe a method to estimate the mass distribution of a gravitational lens and the
position of the sources from combined strong and weak lensing data. The algorithm …

Modeling strong gravitational lenses in order to quantify distortions in the images of
background sources and to reconstruct the mass density in foreground lenses has been a …

We revisit the issue of non-parametric gravitational lens reconstruction and present a new
method to obtain the cluster mass distribution using strong lensing data without using any …
