Crowd-sourced discovery of gravitational lenses. We are a Zooniverse project, which launched in Spring 2013 at http://spacewarps.org. This repository contains code and documentation being developed by the science team.
Two papers on the first dataset we searched for lenses, the CFHTLS, have been published:
- Marshall et al. 2016: "Space Warps I: Crowd-sourcing the Discovery of Gravitational Lenses", MNRAS, 455, 1171
- More et al. 2016: "Space Warps II: New Gravitational Lens Candidates from the CFHTLS Discovered through Citizen Science", MNRAS, 455, 1191
The web app itself is being developed here as part of the Zooniverse project. The simulated lenses used in the training sample are created with SIMCT. If you are interested in building a site like Space Warps using Zooniverse techology, keep an eye on their website or drop them a line.

All our code is free to re-use under the MIT license. If you make use of any of it in your research, please cite us at this website, and as "(Marshall et al. 2016, More et al. 2016)". Please do get in touch though - it would be great to collaborate on improving the SWAP analysis, for example!
