Abstract

Almost all science that can be done with strong gravitational lenses requires knowledge of the lens and source redshifts. The 4MOST Strong Lensing Spectroscopic Legacy Survey (4SLSLS) will follow up strong lens candidates discovered in the Euclid survey and the Legacy Survey of Space and Time. 4SLSLS will provide pairs of redshifts for 10 000 strong-lensing galaxies (lenses) and background galaxies (sources). Velocity dispersions will also be measured for 5000 lenses. This sample will enable discoveries about the evolution of galaxies, the study of intrinsically faint objects and of the cosmological model.
