Abstract:

This talk discusses a general method for estimating contributions to gravitational-wave signals from non-precessing black hole binaries beyond the leading quadrupole order. The method is based on the stationary phase approximation, and it uses the Kerr quasi-normal mode spectrum and phenomenological observations in order to extend known relationships between gravitational multipoles. This method is applied to an existing leading quadrupole order frequency-domain waveform model tuned to Numerical Relativity (known as PhenomD) in order to yield a higher multipole inspiral-merger-ringdown gravitational-wave model. I analyze the performance of this model in terms of mismatches against numerical simulations of binary black hole mergers, and I illustrate examples of its use in parameter estimation.
