Final Report Summary - CALENDS (Clusters And LENsing of Distant Sources) The Clusters And LENsing Distant Galaxies (CALENDS) projects aimed at using the best observationsavailable on massive galaxy clusters and use them as gravitational telescopes to study the galaxies inthe distant Universe. Our goals were to first calibrate the mass distribution of these clusters tounderstand how they magnify the light of distant sources. We used novel techniques toautomatically identify sources producing mirages, i.e. multiple images of the same source galaxy.Complemented by very efficient spectroscopic follow-up using the MUSE instruments, we have beenable to obtain very accurate mass models. We have then started to use these models to understand theproperties of the distant galaxies, which appear in the form of very magnified extended arcs, wherewe can resolve their inner properties such as the formation of stars and the distribution of the gas. Wehave also built a large sample of distant low-mass galaxies at high redshift for which we were able to test the scaling relations between parameters such as size and mass, mass and star formation.
