论文摘要
Ligo和处女座合作对引力波的首次直接测量开辟了新的途径来探索我们的宇宙。这份白皮书概述了在Ligo/处女座带上方的引力波搜索中预期的挑战和收益，特别关注超高频引力波（UHF-GWS），涵盖MHz至GHz范围。在此频率范围内，缺乏已知的天体物理来源为发现在早期和晚期宇宙中运行的标准模型以外的物理学的独特机会，我们重点介绍了一些最有希望的引力来源。我们回顾了一些探测器概念，这些概念已提出来应对这一挑战，并将其预期灵敏度与各种模型中预测的信号强度进行比较。该报告是在2019年10月在意大利ICTP Trieste举行的“高频引力浪潮检测的挑战和机遇”的摘要，该报告为最近发起的超高频引力波（UHF-GW）倡议建立了舞台。
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges and gains expected in gravitational wave searches at frequencies above the LIGO/Virgo band, with a particular focus on Ultra High-Frequency Gravitational Waves (UHF-GWs), covering the MHz to GHz range. The absence of known astrophysical sources in this frequency range provides a unique opportunity to discover physics beyond the Standard Model operating both in the early and late Universe, and we highlight some of the most promising gravitational sources. We review several detector concepts which have been proposed to take up this challenge, and compare their expected sensitivity with the signal strength predicted in various models. This report is the summary of the workshop "Challenges and opportunities of high-frequency gravitational wave detection" held at ICTP Trieste, Italy in October 2019, that set up the stage for the recently launched Ultra-High-Frequency Gravitational Wave (UHF-GW) initiative.
