GANSky -- fast curved sky weak lensing simulations using Generative Adversarial Networks
Supranta S. Boruah, Pier Fiedorowicz, Rafael Garcia +3
Extracting non-Gaussian information from the next generation weak lensing surveys will require fast and accurate full-sky simulations. This is difficult to achieve in practice with…
