Measuring the mass distribution of voids with stacked weak lensing - 4 views

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...

Redshift Drift using Strong Lenses - 9 views

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...
