Abstract

We present the IMRPHENOMXHM frequency domain phenomenological waveform model for the inspiral, merger, and ringdown of quasicircular nonprecessing black hole binaries. The model extends the IMRPHENOMXAS waveform model {[}G. Pratten, S. Husa, C. Garcia-Quiros, M. Colleoni, A. Ramos-Buades, H. Estelles, and R. Jaume, preceding paper, Phys. Rev. D 102, 064001 (2020)], which describes the dominant quadrupole modes l = vertical bar m vertical bar = 2, to the harmonics (l vertical bar m vertical bar) = (2, 1), (3, 3), (3, 2), (4,4), and includes mode mixing effects for the (3,2) spherical harmonic. IMRPHENOMXHM is calibrated against hybrid waveforms, which match an inspiral phase described by the effective-one-body model and post-Newtonian amplitudes for the subdominant harmonics to numerical relativity waveforms and numerical solutions to the perturbative Teukolsky equation for large mass ratios up to 1000.
