It's been very fun/frustrating sitting on these results for the last couple of months 😜
So I'm happy they're out for the rest of the world to see!

Finally, I want to thank the amazing team I've had the privilege to work with over the last couple of months in preparing this paper!
I couldn't find a better group of people to work with, and explore the amazing astrophysical potential our observations provide 🙂

This precise spin measurements also allow us to do some pretty impressive tests of fundamental physics, in addition to the very informative astrophysical constraints.
Again, showing the amount GW observations will be able to help us understand our Universe better in so many different ways!

This is most evident in the very well measured spins of the more massive BH in our binaries.

These two binaries have some pretty exciting properties, with binary configurations nicely hinting towards a likely formation through *at least* a dynamical process, but also potentially with one of the Black Holes in our observed binaries being the remnant from a previous BBH merger!

You're welcome Carl 🙂

Yes to all.

(I don't know, but I'll ask around tomorrow 🙂)

This one is really cool, so a print has been ordered 🙂
