标题： Sensitivity Studies for Third-Generation Gravitational Wave Observatories

摘要： 目前正处在建设中的先进引力波探测器有望直接观测到来自天体物理起源的引力波信号。为了全面开启新兴的引力波天文学领域，提出了下一代引力波探测器——爱因斯坦望远镜。本文描述了爱因斯坦望远镜的灵敏度模型，并研究了由基本噪声源所施加的潜在限制。特别关注的是评估低于10Hz的频率范围，在该范围内，地震噪声、重力梯度噪声、悬挂热噪声和辐射压噪声复杂混合主导。我们开发了迄今为止最准确的第三代探测器灵敏度模型，称为ET-D，其中包括最相关的基础噪声贡献。 显示英文摘要

摘要： Advanced gravitational wave detectors, currently under construction, are expected to directly observe gravitational wave signals of astrophysical origin. The Einstein Telescope, a third-generation gravitational wave detector, has been proposed in order to fully open up the emerging field of gravitational wave astronomy. In this article we describe sensitivity models for the Einstein Telescope and investigate potential limits imposed by fundamental noise sources. A special focus is set on evaluating the frequency band below 10Hz where a complex mixture of seismic, gravity gradient, suspension thermal and radiation pressure noise dominates. We develop the most accurate sensitivity model, referred to as ET-D, for a third-generation detector so far, including the most relevant fundamental noise contributions.
