Discovering New Strong Gravitational Lenses in the DESI Legacy Imaging Surveys

Understand

We have conducted a search for new strong gravitational lensing systems in the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys' Data Release 8.

• We use deep residual neural networks, building on previous work presented in Huang et al.
• (2020).
• These surveys together cover approximately one third of the sky visible from the northern hemisphere, reaching a z band AB magnitude of ~22.5.
