堆芯噪声要求和AMIGO的GW灵敏度

Core Noise Requirements, and GW Sensitivities of AMIGO

Wei-Tou Ni

摘要:

AMIGO -天体动力学中频干涉GW(引力波)观测站是第一代中频GW飞行任务,弥补了高频GW探测器和低频空间GW探测器之间的灵敏度差距。在我们以前的工作中,我们得到了标称臂长为10,000 km的合适的日心轨道编队,它们的第一代时延构形满足频率降噪要求,我们还计算出了推力-燃料友好的恒臂日心轨道编队。在本文中,我们回顾和研究噪声要求,并提出相应的GW灵敏度。从设计白位置噪声和加速度噪声,我们得到的GW灵敏度的第一代迈克尔逊X TDI配置的b-AMIGO(基线AMIGO),AMIGO,和e-AMIGO(增强AMIGO)。鉴于目前的技术发展,我们研究并指出了执行非洲之友组织任务概念的步骤。

英文摘要:

AMIGO - The Astrodynamical Middle-frequency Interferometric GW (Gravitation-Wave) Observatory is a first-generation mid-frequency GW mission bridging the sensitivity gap between the high-frequency GW detectors and low-frequency space GW detectors. In our previous works, we have obtained appropriate heliocentric orbit formations of nominal arm length 10,000 km with their first-generation time-delay configurations satisfying frequency noise reduction requirement, and we have also worked out thrust-fuel friendly constant-arm heliocentric orbit formations. In this paper, we review and study noise requirements and present the corresponding GW sensitivities. From the design white position noises and acceleration noises, we obtain the GW sensitivities for the first-generation Michelson X TDI configuration of b-AMIGO (baseline AMIGO), AMIGO, and e-AMIGO (enhanced AMIGO). In view of the current technology development, we study and indicate steps to implement the AMIGO mission concept.
