This is a quick notebook that performs a rough check against the claimed AGN association with GW190521 in Graham, et al. (2020) now that the LIGO results in Abbott, et al. (2020) and Abbott, et al. (2020) are available.

If you want to try out these sorts of calculations, you can run this notebook or create your own using the Flation Institute Binder via the button above. Note that you will have to re-download the PE samples manually (use curl on the link in the notebook) because they are not stored in the repository.
