标题： Cosmic Explorer: A Submission to the NSF MPSAC ngGW Subcommittee

摘要： 引力波天文学已经彻底改变了人类对宇宙的看法，这一变革源于其他领域无法做到的观测。 本文档描述了一个基于国家科学基金会数十年投资的天文台，它将在未来几十年推动发现：宇宙探索者。 天文学中的重大发现由三个相关改进驱动：更好的灵敏度、更高的精度和打开新的观测窗口。 宇宙探索者承诺实现这三者，并将比LIGO的灵敏度提高一个数量级。 借助已被LIGO在开发过程中证明的技术，宇宙探索者将把引力波前沿推至接近可观测宇宙的边缘。 凭借新设施才能提供的前所未有的灵敏度， 宇宙探索者将做出目前无法预见的发现，特别是因为引力波不仅与电磁观测具有协同效应，还可以进入电磁观测无法探索的宇宙区域。 通过宇宙探索者，科学家可以利用宇宙作为实验室来检验物理定律并研究物质的本质。 宇宙探索者使美国能够继续在引力波科学及其国际下一代天文台网络中的领导地位。 凭借其非凡的发现潜力，宇宙探索者将在天文学、物理学和宇宙学领域提供革命性观测，包括：宇宙时间中的黑洞和中子星、多信使天体物理学与密集物质动力学、极端天体物理学的新探针、基础物理与精确宇宙学、暗物质与早期宇宙。 显示英文摘要

摘要： Gravitational-wave astronomy has revolutionized humanity's view of the universe, a revolution driven by observations that no other field can make. This white paper describes an observatory that builds on decades of investment by the National Science Foundation and that will drive discovery for decades to come: Cosmic Explorer. Major discoveries in astronomy are driven by three related improvements: better sensitivity, higher precision, and opening new observational windows. Cosmic Explorer promises all three and will deliver an order-of-magnitude greater sensitivity than LIGO. Cosmic Explorer will push the gravitational-wave frontier to almost the edge of the observable universe using technologies that have been proven by LIGO during its development. With the unprecedented sensitivity that only a new facility can deliver, Cosmic Explorer will make discoveries that cannot yet be anticipated, especially since gravitational waves are both synergistic with electromagnetic observations and can reach into regions of the universe that electromagnetic observations cannot explore. With Cosmic Explorer, scientists can use the universe as a laboratory to test the laws of physics and study the nature of matter. Cosmic Explorer allows the United States to continue its leading role in gravitational-wave science and the international network of next-generation observatories. With its extraordinary discovery potential, Cosmic Explorer will deliver revolutionary observations across astronomy, physics, and cosmology including: Black Holes and Neutron Stars Throughout Cosmic Time, Multi-Messenger Astrophysics and Dynamics of Dense Matter, New Probes of Extreme Astrophysics, Fundamental Physics and Precision Cosmology, Dark Matter and the Early Universe.
