Today the LIGO/Virgo/KAGRA Collaborations released our fifth catalogue of Gravitational Wave Transients. This is extra exciting for us here at @unlv.edu as the flagship publication (dcc.ligo.org/LIGO-P260015...) was led by Leo Tsukada, a postdoctoral research fellow at the @ncfa.bsky.social.

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!
