Inference of Neutron Star Mass Distributions and the Dense Matter Equation of State from Multi-messenger Observations
Mahmudul Hasan Anik, Andrew W. Steiner, Richard O'Shaughnessy
We construct a combined model to incorporate neutron star (NS) mass measurements with electromagnetic mass-radius constraints and gravitational-wave observations using Bayesian inf…
Limitations in constraining neutron star radii and nuclear properties from inspiral gravitational wave detections
Zhenyu Zhu, Richard O'Shaughnessy
We investigate the constraints on the neutron star equation of state (EoS) and nuclear properties achievable with third-generation gravitational wave detectors using the Fisher inf…
Joint Electromagnetic and Gravitational Wave Inference of Binary Neutron Star Merger GW170817 Using Forward-Modeling Ejecta Predictions
Marko RistiÄ, Richard O'Shaughnessy, Kate Wagner +5
We reassess the capacity for multimessenger inference of AT2017gfo/GW170817 using both kilonova and gravitational wave emission within the context of a recent simulation-based surr…
Astrophysical assumptions and equation of state framework have larger impact on equation of state inference than individual neutron star observations
Atul Kedia, Richard O'Shaughnessy, Leslie Wade +1
The wide range of nuclear densities achieved in neutron stars makes them probes of dense nuclear behavior in the form of the nuclear equation of state (EoS). Studying neutron stars…
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…
