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!

A happy start for my stay @aspenphysics.bsky.social
Excited to learn and work on low-frequency Gravitational Wave science!

A nice Kelvin–Helmholtz instability over the Grand Canyon

Strong approval of today's featured Wikipedia article!
Today's featured Wikipedia article is the one about the Virgo gravitational wave detector.
