Query: Impact of subdominant modes on the interpretation of gravitational-wave
  signals from heavy binary black hole systems   Over the past year, a handful of new gravitational wave models have been
developed to include multiple harmonic modes thereby enabling for the first
time fully Bayesian inference studies including higher modes to be performed.
Using one recently-developed numerical relativity surrogate model,
NRHybSur3dq8, we investigate the importance of higher modes on parameter
inference of coalescing massive binary black holes. We focus on examples
relevant to the current three-detector network of observatories, with a
detector-frame mass set to $120 M_\odot$ and with signal amplitude values that
are consistent with plausible candidates for the next few observing runs. We
show that for such systems the higher mode content will be important for
interpreting coalescing binary black holes, reducing systematic bias, and
computing properties of the remnant object. Even for comparable-mass binaries
and at low signal amplitude, the omission of higher modes can influence
posterior probability distributions. We discuss the impact of our results on
source population inference and self-consistency tests of general relativity.
Our work can be used to better understand asymmetric binary black hole merger
events, such as GW190412. Higher modes are critical for such systems, and their
omission usually produces substantial parameter biases.
