eLISA探测类似于GW150914的星系双星黑洞的前景

Prospects of eLISA for Detecting Galactic Binary Black Holes Similar to GW150914

摘要:

我们讨论了eLISA探测类似于GW150914的银河系双黑洞的引力波的前景。对于与当前观察一致的共动合并率,eLISA可能识别出至少一个具有足够信噪比的BBH。此外,eLISA有可能测量小至$e\sim 0.02$的BBH偏心率,对应于10 Hz时的残差值$e\sim 10^{-6}$。因此,eLISA可以为我们提供关键信息,以了解像GW150914这样相对大质量的BBH的形成过程。我们还推导出一个简单的标度关系的预期数量的可检测的银河系BBH。

英文摘要:

We discuss the prospects of eLISA for detecting gravitational waves (GWs) from Galactic binary black holes (BBHs) similar to GW150914. For a comoving merger rate that is consistent with current observation, eLISA is likely to identify at least one BBH with a sufficient signal-to-noise ratio. In addition, eLISA has a potential to measure the eccentricity of the BBH as small as $e\sim 0.02$, corresponding to the residual value $e\sim 10^{-6}$ at 10Hz. Therefore, eLISA could provide us with a crucial information to understand the formation processes of relatively massive BBHs like GW150914. We also derive a simple scaling relation for the expected number of detectable Galactic BBHs.
