论文摘要
重力波为在极端条件下探测一般相对性（GR）的窗口。最近对GW190412和GW190814的观察结果是独特的高质量收入，可以使重力波谐波的观察超出主导$（\ ell，m）=（2，2）$模式。使用这些事件，我们通过允许从亚占主导谐波测量的源参数来搜索GR以外的物理学，以偏离主导模式的源。所有结果都与GR一致。我们按照$（\ ell，m）=（3，3）$模式来限制chirp质量，当我们允许亚显点模式的质量和旋转时，在$ 0 _ { - 3}^{ - 3}^{+5} \％$中。如果我们仅允许质量参数偏离，我们将限制$（3，3）$模式的chirp质量在$ \ pm1 \％$ the gr的期望值的$ \ pm1 \％$之内。
Gravitational waves provide a window to probe general relativity (GR) under extreme conditions. The recent observations of GW190412 and GW190814 are unique high-mass-ratio mergers that enable the observation of gravitational-wave harmonics beyond the dominant $(\ell, m) = (2, 2)$ mode. Using these events, we search for physics beyond GR by allowing the source parameters measured from the sub-dominant harmonics to deviate from that of the dominant mode. All results are consistent with GR. We constrain the chirp mass as measured by the $(\ell, m) = (3, 3)$ mode to be within $0_{-3}^{+5}\%$ of the dominant mode when we allow both the masses and spins of the sub-dominant modes to deviate. If we allow only the mass parameters to deviate, we constrain the chirp mass of the $(3, 3)$ mode to be within $\pm1\%$ of the expected value from GR.
