Accurate characterization of the stochastic gravitational-wave background with pulsar timing arrays by likelihood reweighting
Sophie Hourihane, Patrick Meyers, Aaron Johnson +2
An isotropic stochastic background of nanohertz gravitational waves creates excess residual power in pulsar-timing-array datasets, with characteristic inter-pulsar correlations des…
Concurrent estimation of noise and compact-binary signal parameters in gravitational-wave data
Cailin Plunkett, Sophie Hourihane, Katerina Chatziioannou
Gravitational-wave parameter estimation for compact binary signals typically relies on sequential estimation of the properties of the detector Gaussian noise and of the binary para…
The curious case of GW200129: interplay between spin-precession inference and data-quality issues
Ethan Payne, Sophie Hourihane, Jacob Golomb +3
Measurement of spin-precession in black hole binary mergers observed with gravitational waves is an exciting milestone as it relates to both general relativistic dynamics and astro…
Accurate modeling and mitigation of overlapping signals and glitches in gravitational-wave data
Sophie Hourihane, Katerina Chatziioannou, Marcella Wijngaarden +3
The increasing sensitivity of gravitational-wave detectors has brought about an increase in the rate of astrophysical signal detections as well as the rate of "glitches"; transient…
