论文摘要
灵感紧凑型二进制文件的偏心率可以大大改善黑暗警报器的距离推断和来源定位。在本文中，我们继续研究太空植物原子干涉重力波检测器AEDGE，并研究了偏心率对Adge在中频中观察到的黑暗警报器的影响。我们模拟了五种类型的典型紧凑型二进制文件，其组件质量从$ 1-100〜M _ {\ odot} $不等。距离推断和定位的最大改进可能高达1.5--3个数量级。然后，我们构建了Adge在五年内观察到的黑暗警报器的目录。我们发现偏心率对于可以独特地识别的宿主星系的金黄色二元黑洞（BBH）至关重要。只有5--10 Golden Dark BBHS可以获得2％的精度测量$ H_0 $，这足以仲裁哈勃张力。不管偏心率如何，Adge还可以观察到具有独特的宿主星系的数十个金色的二元中子星（BNS）和中子星 - 黑孔二进制二进制（NSBH）。这些金色的黑暗警报器可以用作早期警告，以便对高频带中重力波的后续观察以及对它们的电磁对应物进行搜索。我们的结果表明，偏心率是GWS与原子干涉仪中中频的检测，数据分析和应用中的关键因素。
Eccentricity of the inspiraling compact binaries can greatly improve the distance inference and source localization of dark sirens. In this paper, we continue the research for the space-borne atom interferometric gravitational-wave detector AEDGE and investigate the effects of eccentricity on the dark sirens observed by AEDGE in the mid-band. We simulate five types of typical compact binaries with component mass ranging from $1-100~M_{\odot}$. The largest improvement for both distance inference and localization can be as much as 1.5--3 orders of magnitude. We then construct the catalogs of dark sirens observed by AEDGE in five years. We find eccentricity is crucial to the detection of golden binary black holes (BBH) whose host galaxy can be uniquely identified. With only 5--10 golden dark BBHs one can obtain a 2 percent precision measurement of $H_0$ which is sufficient to arbitrate the Hubble tension. Regardless of eccentricity, AEDGE can also observe tens of golden binary neutron stars (BNS) and neutron star--black hole binaries (NSBH) with unique host galaxies. These golden dark sirens can serve as early warnings for the follow-up observations of gravitational waves in the high frequency band as well as the search of their electromagnetic counterparts. Our results show eccentricity is a crucial factor in the detection, data analysis, and application of GWs with the atom interferometers in the mid-band.
