Lens Search

We search for lenses in DESI imaging and spectroscopic data, using ML/AI and “classical” techniques.

Hubble Space Telescope Snap Programs

• This Snap program (GO 18085, PI: Huang) is built upon the newest lens search we conducted and our paper will be submitted soon.
• This program (GO 15867, PI: Huang) aims to confirm some of the best lens candidates found in our first two lens search papers below, H20 and H21.

Strong Lens Search Series

1. Deep-learning searches in DESI imaging using ResNet and EfficientNet; ~4,000 new lenses across four search papers:
   • Huang et al. 2020 (H20)
   • Huang et al. 2021 (H21)
   • Storfer et al. 2024
   • Inchausti et al. 2025
2. Autocorrelation
   • Dawes et al. 2022 : 434 lensed quasar candidates found in DESI imaging quasar catalog.
3. Difference Imaging
   • Sheu et al. 2023 : Restroscopic search of lenses supernovae in DESI imaging quasar catalog.
   • Sheu et al. 2024a : Lensed quasars found via a time-variabilty search in DESI imaging quasar catalog.
