Waveform systematics in the gravitational-wave inference of tidal parameters

November 19, 2021
Recorded 19 November 2021. Rossella Gamba of Friedrich-Schiller-Universit├Ąt presents "Waveform systematics in the gravitational-wave inference of tidal parameters and equation of state from binary neutron star signals" at IPAM's Workshop III: Source inference and parameter estimation in Gravitational Wave Astronomy. Abstract: Gravitational-wave signals from binary neutron star coalescences carry information about the star's equation of state in their tidal signatures. A major issue in the inference of the tidal parameters (or directly of the equation of state) is the systematic error introduced by waveform approximants. Here I will discuss their impact on the loud, high signal to noise ratio events that will be observed by advanced and third generation detectors, and show how current state of the art waveform models, including those from numerical relativity, are insufficient to unequivocally infer equation of state constraints from Gravitational wave parameter estimation from the loudest (and potentially most informative) events.
