Abstract
Black holes are the remnants of the most massive of stars and characterising their population using gravitational wave (GW) observations can help us understanding the astrophysical processes governing the life and death of stars. In this picture, non-parametric methods represent an excellent agnostic tool to describe our observations and guide the development of new astrophysical models; on the downside, they lack the interpretability carried by physically informed models. In this talk, after a brief introduction on GW astrophysics and non-parametric methods, I will present a way to interpret non-parametric results in terms of astrophysical models using a map between simplexes induced by the Dirichlet process.
