Do both black holes spin in merging binaries? Evidence from GWTC-4 and astrophysical implications

Christian Adamcewicz, Nir Guttman, Paul D. Lasky +1

Angular momentum transport in high-mass stars is commonly modeled by extrapolating the behavior of better-observed low-mass stars. According to the conventional picture, the cores…
