Description
We investigate the prospect of performing binary black hole (BBH) nature tests using spin-induced multipole moment (SIQM) measurements when the binary is fully precessing. As SIQM is strongly degenerate with spin parameters, we are interested in the degeneracies the SIQM parameter has with spin precession. We extend the previous SIQM-based BBH nature tests by incorporating two-parameter spin-precession effects, studying the effects beyond the leading harmonic in the gravitational waveform for binaries with various mass and spin combinations. We also report the posterior distributions on the SIQM parameter on the observed gravitational wave events through the first three observing runs of the ground-based detectors employing IMRPhenomXP and IMRPhenomXPHM.
