论文摘要
引力波(GW)源的速度提供了有关其形成和进化过程的重要信息。先前的研究将多普勒对GWS阶段的影响视为源速度的潜在特征。但是,多普勒移位仅说明波矢量的时间成分,而原理运动也影响了空间成分。本文分析了GWS的后一种效应,称为光的``差异'',并应用于加速源的波形建模。我们表明,在两个天体物理场景中可以检测到其他畸变相移,即,由于GW辐射而导致的后退二进制黑洞(BBH),在三个系统中是BBH。我们的结果表明,在波形模板中添加畸变的相移可能会显着增强移动源的可检测性。
The velocity of a gravitational wave (GW) source provides crucial information about its formation and evolution processes. Previous studies considered the Doppler effect on the phase of GWs as a potential signature of a time-dependent velocity of the source. However, the Doppler shift only accounts for the time component of the wave vector, and in principle motion also affects the spatial components. The latter effect, known as ``aberration'' for light, is analyzed in this paper for GWs and applied to the waveform modeling of an accelerating source. We show that the additional aberrational phase shift could be detectable in two astrophysical scenarios, namely, a recoiling binary black hole (BBH) due to GW radiation and a BBH in a triple system. Our results suggest that adding the aberrational phase shift in the waveform templates could significantly enhance the detectability of moving sources.
