Evidence for additional structure in the effective spin distribution hints at multiple formation pathways in GWTC-5.0
Sofia Alvarez-Lopez, Jack Heinzel, Salvatore Vitale
The distribution of the effective inspiral spin () of the binary black holes detected by LIGO-Virgo-KAGRA can shed light on their formation pathways. We analyze th…

No model-independent evidence for a peak in binary black hole spin (mis)alignments
Noah E. Wolfe, Salvatore Vitale, Michael Zevin
The degree of black-hole spin-orbit misalignment ("tilts") in the astrophysical population could be a powerful diagnostic to distinguish between binary formation in isolation, in d…

Neural Bayesian updates to populations with growing gravitational-wave catalogs
Noah E. Wolfe, Matthew Mould, John Veitch +1
As gravitational-wave catalogs grow, they will become increasingly computationally expensive to analyze in their entirety, especially when inferring astrophysical source population…
