The Strong Gravitational Lens Finding Challenge

Understand

Large scale imaging surveys will increase the number of galaxy-scale strong lensing candidates by maybe three orders of magnitudes beyond the number known today.

• Finding these rare objects will require picking them out of at least tens of millions of images and deriving scientific results from them will require quantifying the efficiency and bias of any search method.
• To achieve these objectives automated methods must be developed.
• Because gravitational lenses are rare objects reducing false positives will be particularly important.
