Achieving these cosmological goals requires many lensed transients with precise time-delay measurements 4. If the source is variable, it can be used to constrain the cosmic expansion rate 2 and dark energy models 3. When the light from a distant object passes very near to a foreground galaxy or cluster, gravitational lensing can cause it to appear as multiple images on the sky 1.
