Context. The Hubble tension, revealed by a ~5σ discrepancy between measurements of the Hubble-Lemaitre constant among observations of the early and local Universe, is one of the most significant problems in modern cosmology. In order to better unders... Read More about Discovering strongly lensed quasar candidates with catalogue-based methods from DESI Legacy Surveys.
