论文摘要
建议一些大规模的实验设施和空间误差来探测重力波（GW）频谱的宇宙。在这里，我们提出了宇宙学的重力波登起观测（GLOC） - NASA Artemis时代的第一个概念设计，用于月球上的GW天文台。使用可行的干涉仪技术，我们发现基于月球的天文台非常适合探测DECI-Hz至5 Hz之间的GW频率，这是一种天体物理上丰富的机构，对地球和空间基于空间的探测器非常具有挑战性。 GLOC可以用中子星，恒星和中等质量黑洞调查二进制物，以$ \ gtrsim 70 \％$ $ \％的宇宙体积，而没有明显的背景污染。 $ \ MATHCAL {O}（1〜 \ MATHRM {Hz}）$的灵敏度允许一个唯一的窗口校准IA Supernovae类型。 GLOC以最终的灵敏度限制将Hubble扩展率追溯到Redshift $ Z \ SIM 3 $和测试一般相对论以及$λ$ CDM COSMOLOGY最高$ Z \ sim 350 $。
Several large-scale experimental facilities and space-missions are being suggested to probe the universe across the gravitational-wave (GW) spectrum. Here we propose Gravitational-wave Lunar Observatory for Cosmology (GLOC) - the first concept design in the NASA Artemis era for a GW observatory on the Moon. Using feasible interferometer technologies, we find that a lunar-based observatory is ideal for probing GW frequencies in the range between deci-Hz to 5 Hz, an astrophysically rich regime that is very challenging for both Earth- and space-based detectors. GLOC can survey binaries with neutron stars, stellar and intermediate-mass black holes to $\gtrsim 70\%$ of the observable volume of our universe without significant background contamination. The sensitivity at $\mathcal{O}(1~\mathrm{Hz})$ allows a unique window into calibrating Type Ia supernovae. At its ultimate sensitivity limits, GLOC would trace the Hubble expansion rate up to redshift $z \sim 3$ and test General Relativity and $Λ$CDM cosmology up to $z\sim 350$.
