Effects of waveform systematics on inferences of neutron star population properties and the nuclear equation of state
Anjali B. Yelikar, Richard O'Shaughnessy, Daniel Wysocki +1
Gravitational waves from inspiralling neutron stars carry information about matter at extreme gravity and density. The binary neutron star (BNS) event GW170817 provided, for the fi…
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…
Expanding RIFT: Improving performance for GW parameter inference
J. Wofford, A. Yelikar, H. Gallagher +10
The Rapid Iterative FiTting (RIFT) parameter inference algorithm provides a framework for efficient, highly-parallelized parameter inference for GW sources. In this paper, we summa…
Flexible and Fast Estimation of Binary Merger Population Distributions with Adaptive KDE
Jam Sadiq, Thomas Dent, Daniel Wysocki
The LIGO Scientific, Virgo and KAGRA Collaborations recently released the third gravitational wave transient catalog or GWTC-3, significantly expanding the number of gravitational…
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…
All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369
Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…
Inferring the neutron star equation of state simultaneously with the population of merging neutron stars
Daniel Wysocki, Richard O'Shaughnessy, Leslie Wade +1
Observations of the properties of multiple coalescing neutron stars will simultaneously provide insight into neutron star mass and spin distribution, the neutron star merger rate,…
Impact of subdominant modes on the interpretation of gravitational-wave signals from heavy binary black hole systems
Feroz H. Shaik, Jacob Lange, Scott E. Field +5
Over the past year, a handful of new gravitational wave models have been developed to include multiple harmonic modes thereby enabling for the first time fully Bayesian inference s…
Reconstructing phenomenological distributions of compact binaries via gravitational wave observations
Daniel Wysocki, Jacob Lange, Richard O'Shaughnessy
Gravitational wave measurements will provide insight into the population of coalescing compact binaries throughout the universe. We describe and demonstrate a flexible parametric m…
Inferences about the distribution, merger rate, and evolutionary processes of compact binaries from gravitational wave observations
Daniel Wysocki
We are living through the dawn of the era of gravitational wave astronomy. Our first glances through this new window upon the sky has revealed a new population of objects. Since it…
