A Foundation for Gravitational-Wave Population Inference within the LISA Global Fit
Alexander W. Criswell, Sharan Banagiri, Vera Delfavero +3
Population inference in gravitational-wave astronomy allows us to connect individual detections to the astrophysics of compact objects and their environments. Current approaches em…
Prospects for the formation of GW231123 from the AGN channel
V. Delfavero, S. Ray, H. E. Cook +6
The recent binary black hole (BBH) merger GW231123 consisted of the merger of two intermediate mass black holes (IMBH) which appear to have large spin magnitudes. Active galactic n…
Realistic predictions for Gaia black hole discoveries: comparison of isolated binary and dynamical formation models
Pranav Nagarajan, Kareem El-Badry, Chirag Chawla +6
Astrometry from Gaia has enabled discovery of three dormant black holes (BHs) in au-scale binaries. Numerous models have been proposed to explain their formation, including several…
McFACTS II: Mass Ratio--Effective Spin Relationship of Black Hole Mergers in the AGN Channel
Harrison E. Cook, Barry McKernan, K. E. Saavik Ford +6
We use the Monte Carlo For AGN (active galactic nucleus) Channel Testing and Simulation (McFACTS, https://www.github.com/mcfacts/mcfacts) code to study the effect of AGN disk and n…
McFacts III: Compact binary mergers from AGN disks over an entire synthetic universe
Vera Delfavero, K. E. Saavik Ford, Barry McKernan +6
The Active Galactic Nuclei (AGN) channel for the formation of binary black hole (BBH) mergers has been previously studied as a potential formation channel for the merging compact b…
McFACTS I: Testing the LVK AGN channel with Monte Carlo For AGN Channel Testing & Simulation (McFACTS)
Barry McKernan, K. E. Saavik Ford, Harrison E. Cook +6
Active galactic nuclei (AGN) are a promising source of the binary black hole (BBH) mergers observed in gravitational waves with LIGO-Virgo-Kagra (LVK). Constraining the AGN channel…
