Including higher order multipoles in gravitational-wave models for precessing binary black holes
Sebastian Khan, Frank Ohme, Katerina Chatziioannou +1
Estimates of the source parameters of gravitational-wave (GW) events produced by compact binary mergers rely on theoretical models for the GW signal. We present the first frequency…
Multi-waveform inference of gravitational waves
Gregory Ashton, Sebastian Khan
Bayesian inference of gravitational wave signals is subject to systematic error due to modelling uncertainty in waveform signal models, coined approximants. A growing collection of…
Improving the NRTidal model for binary neutron star systems
Tim Dietrich, Anuradha Samajdar, Sebastian Khan +3
Accurate and fast gravitational waveform (GW) models are essential to extract information about the properties of compact binary systems that generate GWs. Building on previous wor…
On the properties of the massive binary black hole merger GW170729
Katerina Chatziioannou, Roberto Cotesta, Sudarshan Ghonge +53
We present a detailed investigation into the properties of GW170729, the gravitational wave with the most massive and distant source confirmed to date. We employ an extensive set o…
