Narrow Population Inference Enhanced by Analytical Likelihood Models
Meesum Qazalbash, Sophiya Mehra, Muhammad Zeeshan +2
The growing catalog of gravitational-wave events has revealed substantial diversity in the properties of compact-binary mergers. However, commonly used population-inference methods…
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…
McFACTS. IV. Electromagnetic Counterparts to AGN-disk-embedded Binary Black Hole Mergers
Emily McPike, Rosalba Perna, K. E. Saavik Ford +10
The accretion disks of active galactic nuclei (AGNs) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GWs…
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…
Recovering Injected Astrophysics from the LISA Galactic Double White Dwarf Binaries
Vera Delfavero, Katelyn Breivik, Sarah Thiele +2
We present the successful recovery of common envelope ejection efficiency assumed in a simulated population of double white dwarf binaries like those which may be observed by the f…
Iteratively Comparing Gravitational-Wave Observations to the Evolution of Massive Stellar Binaries
Vera Delfavero, Richard O'Shaughnessy, Krzysztof Belczynski +2
Gravitational-wave observations have the capability to strongly differentiate between different assumptions for how binary compact objects form. In this work, we show how to carefu…
Gravitational wave source populations: Disentangling an AGN component
V. Gayathri, Daniel Wysocki, Y. Yang +4
The astrophysical origin of the over 90 compact binary mergers discovered by the LIGO and Virgo gravitational wave observatories is an open question. While the unusual mass and spi…
Compressed Parametric and Non-Parametric Approximations to the Gravitational Wave Likelihood
Vera Delfavero, Richard O'Shaughnessy, Daniel Wysocki +1
Gravitational-wave observations of quasicircular compact binary mergers imply complicated posterior measurements of their parameters. Though Gaussian approximations to the pertinen…
A Nuclear Equation of State Inferred from Stellar r-process Abundances
Erika M. Holmbeck, Richard O'Shaughnessy, Vera Delfavero +1
Binary neutron star mergers (NSMs) have been confirmed as one source of the heaviest observable elements made by the rapid neutron-capture (r-) process. However, modeling NSM outfl…
Normal Approximate Likelihoods to Gravitational Wave Events
Vera Delfavero, Richard O'Shaughnessy, Daniel Wysocki +1
Gravitational wave observations of quasicircular compact binary mergers in principle provide an arbitrarily complex likelihood over eight independent intrinsic parameters: the mass…
