当前引力波（GW）宇宙学面临两大瓶颈：明亮信号源的电磁对应体稀缺，以及暗信号源的星系目录系统不确定性。我们提出一种纯引力波解决方案，利用集成宇宙学记忆（ICM）——膨胀宇宙时空几何中编码的累积引力波应变。源发出的引力波瞬变提供光度距离，而ICM则累积了宇宙膨胀历史的数学上截然不同的积分。我们证明，从单次双致密星并合事件中提取这两个可观测量，可完全打破引力领域内的距离-红简并性。这为第三代引力波探测器网络建立了一种新型、无需星系目录的暗信号源框架。关键的是，由此得到的晚期暗能量约束对局部膨胀率仅呈弱敏感性，是一种稳健的宇宙学探针，有望缓解哈勃常数（H0）张力的影响。
英文摘要
Gravitational-wave (GW) cosmology is currently bottlenecked by the scarcity of electromagnetic counterparts for bright sirens and the systematic uncertainties of galaxy catalogs for dark sirens. We propose a purely gravitational resolution using the Integrated Cosmological Memory (ICM)-the cumulative GW strain encoded in the spacetime geometry of an expanding Universe. While the GW transient emitted by the source provides the luminosity distance, the ICM accumulates a mathematically distinct integral of the cosmic expansion history. We demonstrate that extracting both observables from a single binary merger completely breaks the distance-redshift degeneracy within the gravitational sector. This establishes a novel, catalog-free dark siren framework for third-generation GW detector networks. Crucially, the resulting constraints on late-time dark energy are only weakly sensitive to the local expansion rate, providing a robust cosmological probe that can potentially mitigate the impact of the H0 tension.
