论文摘要
丽莎可以从具有较大信噪比的大型黑洞二进制合并中检测出较高的响应重力波信号的谐波。最庞大的黑洞二进制文件更有可能具有电磁对应物，并且灵感不会对它们的信噪比贡献。在这里，我们解决以下问题：我们只能使用RINGDOWN的LISA观察提取二进制参数并本地化源吗？当我们检测到长期寿命的灵感信号时，由于Lisa在太阳周围的运动而引起的幅度和相位的调制可以用来解开源位置和方向，但是它们不能用于非常短暂的持久性信号。我们表明（i）我们仍然可以通过仔细组合多个响声谐波来测量高质量二进制文件的质量比和倾斜度，并且（ii）我们可以通过依靠各种谐波的相对幅度和各个相位来限制天空位置和亮度距离，如在不同的Lisa通道中所测量的。
LISA can detect higher harmonics of the ringdown gravitational-wave signal from massive black-hole binary mergers with large signal-to-noise ratio. The most massive black-hole binaries are more likely to have electromagnetic counterparts, and the inspiral will contribute little to their signal-to-noise ratio. Here we address the following question: can we extract the binary parameters and localize the source using LISA observations of the ringdown only? Modulations of the amplitude and phase due to LISA's motion around the Sun can be used to disentangle the source location and orientation when we detect the long-lived inspiral signal, but they can not be used for ringdown-dominated signals, which are very short-lived. We show that (i) we can still measure the mass ratio and inclination of high-mass binaries by carefully combining multiple ringdown harmonics, and (ii) we can constrain the sky location and luminosity distance by relying on the relative amplitudes and phases of various harmonics, as measured in different LISA channels.
