Comparing effective-one-body and gravitational self-force results as tools for third-generation gravitational wave detectors
2023
Abstrakt
Gravitational self-force theory and the effective-one-body (EOB) formalism are two different approaches to the two-body problem in general relativity, both suited to describe black hole binary evolutions, but natively pertaining to different domains of validity. After briefly introducing the two formalisms, I will present a comparison between the related gravitational waveforms, both in the time domain and in the frequency domain, locating the region of largest agreement.
I will then introduce some updates to the EOB model, paving the way for accurate waveform modeling for third-generation detectors.
