The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

Studies of galaxy clusters have proved crucial in helping to establish the standard model of
cosmology, with a Universe dominated by dark matter and dark energy. A theoretical basis …

We present a new strong lensing (SL) model of the Hubble Frontier Fields (HFF) galaxy
cluster Abell 2744, at z= 0.3072, by exploiting archival Hubble Space Telescope (HST) …

Context. Spectroscopic surveys of massive galaxy clusters reveal the properties of faint
background galaxies thanks to the magnification provided by strong gravitational lensing …

We present a candidate for the most distant galaxy known to date with a photometric redshift
of z= 10.7+ 0.6− 0.4 (95% confidence limits; with z< 9.5 galaxies of known types ruled out at …

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 …

The current standard model of cosmology successfully describes a variety of measurements,
but the nature of its main ingredients, dark matter and dark energy, remains unknown. is a …

We present our lens mass model of SMACS J0723. 3− 7327, the first strong gravitational
lens observed by the James Webb Space Telescope (JWST). We use data from the Hubble …

Clusters of galaxies are excellent locations to probe the distribution of baryons and dark
matter (DM) over a wide range of scales. We study a sample of seven massive (M 200= 0.4 …

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 …
