On the Astrophysical Origin of Binary Black Hole Subpopulations: A Tale of Three Channels?

Anarya Ray, Shirsha Mukherjee, Michael Zevin +1

There is increasing evidence for multiple binary black hole~(BBH) subpopulations in the cumulative gravitational wave catalog by the LIGO-Virgo-KAGRA Collaboration. The astrophysic…

Las Cumbres Observatory Gravitational-Wave Follow-up in the Third and Fourth Observing Runs: Strengths and Weaknesses of a Rapid Response Galaxy Targeted Strategy

Ido Keinan, Iair Arcavi, D. Andrew Howell +34

We present a summary of gravitational-wave (GW) follow-up using the Las Cumbres Observatory global network of telescopes during the third (O3) and fourth (O4) observing runs of the…

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…

Astrophysical Implications of Eccentricity in Gravitational Waves from Neutron Star-Black Hole Binaries

Isobel Romero-Shaw, Jakob Stegmann, Gonzalo Morras +2

The gravitational-wave signal from the neutron star-black hole (NSBH) merger GW200105 is consistent with this binary having significant orbital eccentricity close to merger. This r…

Inference on inner galaxy structure via gravitational waves from supermassive binaries

Yifan Chen, Matthias Daniel, Daniel J. D'Orazio +107

The detection of a stochastic gravitational wave background by pulsar-timing arrays indicates the presence of a population of supermassive black hole binaries. Although the observe…
