new cosmological tests with LIGO

Kate Storey-Fisher (NYU) and I had a wide-ranging conversation with Will Farr (Flatiron) about uses of LIGO sources for cosmological studies. We all have the intuition that there is lots of space in the literature for new approaches, but we can't quite figure out where to position ourselves. I like the idea of going fully frequentist, because most of the competition is purely Bayesian. The ideas I like best so far involve something like correlations between LIGO error boxes and large-scale structure surveys.
