Hubble Constant Measurement from Three Large-separation Quasars Strongly Lensed by Galaxy Clusters

Tension between cosmic microwave background–based and distance ladder–based determinations of the Hubble constant H _0 motivates the pursuit of independent methods that are not subject to the same systematic effects. A promising alternative, proposed by Refsdal in 1964, relies on the inverse scaling...
