Strong lensing in galaxy clusters probes properties of dense cores of dark
matter halos in mass, studies the distant universe at flux levels and spatial
resolutions otherwise unavailable, and constrains cosmological models
independently. The next-generation large scale sky imaging surveys are expected
to discover thousands of cluster-scale strong lenses, which would lead to
unprecedented opportunities for applying cluster-scale strong lenses to solve
astrophysical and cosmological problems. However, the large dataset challenges
astronomers to identify and extract strong lensing signals, particularly …
