Waveform Systematics in the Gravitational-Wave Inference of Tidal Parameters

Explore the complexities of gravitational-wave inference in binary neutron star signals through this 46-minute conference talk by Rossella Gamba. Delve into the challenges of extracting tidal parameters and equation of state information from gravitational-wave data, focusing on the systematic errors introduced by waveform approximants. Examine the impact of these errors on high signal-to-noise ratio events observable by advanced and third-generation detectors. Discover why current state-of-the-art waveform models, including those from numerical relativity, are insufficient for unambiguous equation of state constraints in gravitational wave parameter estimation. Learn about various waveform models, including PN, EOB, and Phenom, and their limitations. Investigate the problem of parameter estimation and methodologies for studying systematics. Analyze injection studies, real data from GW170817, and future prospects with third-generation detectors. Gain insights into the importance of spin-induced effects and the role of numerical relativity in addressing these challenges.
