To construct analytical templates of IMR waveforms, hybrid waveforms are constructed by matching numerical relativity simulations describing the merger and ringdown with post-Newtonian waveforms describing the early inspiral. Neglecting the subdominant modes of the radiation (beyond the leading quadrupole modes) can lead to appreciable loss of signal to noise ratio and systematic errors in the parameters. In this work we present an analytical model of IMR waveforms for non-spinning binary black holes that include the effect of nonquadrupole modes. |
