A gravitationally lensed quasar with quadruple images separated by 14.62|[thinsp]|arcseconds
Gravitational lensing is a powerful tool for the study of the distribution of dark matter in the Universe. The cold-dark-matter model of the formation of large-scale structures (that is, clusters of galaxies and even larger assemblies) predicts the existence of quasars gravitationally lensed by concentrations of dark matter so massive that the quasar images would be split by over 7|[thinsp]|arcsec.
