Strong Gravitational Lenses in the Era of Wide-Field Surveys

Thanks Eric. How bright do you think the lensed quasars need to be? How does the trade off between flux and timedelay work out? I looked into redshift drift a few years ago, and based on the assump...

Higuchi et al. want to detect the signal of voids in large weak lensing data. They use N body simulations, and a clever void finder to make a huge stack of voids; this gives a detectable weak lensi...
