Using machine learning trained on real data, and applied on DESI Legacy Imaging Surveys Data Release 8th has uncovered the 1210 new strong lens candidates, approximately the double of known lenses. This research was presented in the paper Discovering New Strong Gravitational Lenses in the DESI Legacy Imaging Surveys to appear in The Astrophysical Journal. These new lens candidates can be used to make new measurements of cosmological parameters. See the Science Release Note.
