Effective-one-body waveforms for binary neutron stars using surrogate models
Effective-one-body waveforms for binary neutron stars using surrogate models
Gravitational-wave observations of binary neutron star systems can provide information about the masses, spins, and structure of neutron stars. However, this requires accurate and computationally efficient waveform models that take $\ensuremath{\lesssim}1\text{ }\text{ }\mathrm{s}$ to evaluate for use in Bayesian parameter estimation codes that perform $1{0}^{7}--1{0}^{8}$ waveform evaluations. We present a …
