We present the Dark Energy Spectroscopic Instrument (DESI) Strong Lens Foundry. discovered $\sim 3500$ new strong gravitational lens candidates in DESI Legacy Imaging Surveys using residual neural networks (ResNet). observed a subset (51) of our Hubble Space Telescope (HST). All them were confirmed to be lenses. also briefly describe spectroscopic follow-up observations by and Keck NIRES programs. From this very rich dataset, number studies will carried out, including evaluating quality...
Gravitational lensing provides unique insights into astrophysics and cosmology, including the determination of galaxy mass profiles constraining cosmological parameters. We present spectroscopic confirmation lens modeling strong system DESI-253.2534+26.8843, discovered in Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys data. This consists a massive elliptical surrounded by four blue images forming an Einstein Cross pattern. obtained observations this using Multi Unit...
