hey yall, here's a #science thread!

One of the larger excitements of my past couple months is finally getting this paper out -- it's up on arXiv tonight and accepted to ApJL (with an AAS Nova highlight on the way)

This paper is trying to answer the question of how many really big black holes are in our corner of the universe and the consequence of that number.

We think that our work substantially refines the census of black holes more than about a billion times the mass of the sun, which places constraints on the evolution of massive galaxies over the past couple billion years and furthers our understanding of the cosmic gravitational wave background

In this thread I'll tell ya how we did it! Let's dive in!
