摘要

天基激光干涉仪、LISA、太极和天琴的目标是在 2030 年代观测毫赫兹引力波。多个天基探测器的联合观测具有显著优势。在这项工作中，我们回顾了对联合天基引力波探测器网络的研究和调查，以强调：1）对大质量双黑洞（BBH）凝聚和宇宙学意义上的引力波警报的高精度天空定位；2）在随机引力波背景观测中检验奇偶性违反的有效性；3）减去星系前景的效率；4）恒星质量BBH观测的改进。我们通过在大质量 BBH 观测和随机 GW 背景观测之间进行权衡，考察了替代网络。

On networks of space-based gravitational-wave detectors

The space-based laser interferometers, LISA, Taiji and TianQin, are targeting to observe milliHz gravitational waves (GWs) in the 2030s. The joint observations from multiple space-based detectors yield significant advantages. In this work, we recap the studies and investigations for the joint space-based GW detector networks to highlight: 1) the high precision of sky localization for the massive binary black hole (BBH) coalescences and the GW sirens in the cosmological implication, 2) the effectiveness to test the parity violation in the stochastic GW background observations, 3) the efficiency of subtracting galactic foreground, 4) the improvement in stellar-mass BBH observations. We inspect alternative networks by trading off massive BBH observations and stochastic GW background observation.
