Space-based gravitational wave detectors based on the Laser Interferometer Space Antenna (LISA) design operate by synthesizing one or more interferometers from fringe velocity measurements generated by changes in the light travel time between three spacecraft in a special set of drag-free heliocentric orbits. These orbits determine the inclination of the synthesized interferometer with respect to the ecliptic plane. Once these spacecraft are placed in their orbits, the orientation of the interferometers at any future time is fixed by Kepler's Laws based on the initial orientation of the spacecraft constellation, which may be freely chosen. Over the course of a full solar orbit, the initial orientation determines a set of locations on the sky were the detector has greatest sensitivity to gravitational waves as well as a set of locations where nulls in the detector response fall. By artful choice of the initial orientation, we can choose to optimize or suppress the antennas sensitivity to sources whose location may be known in advance (e.g., the Galactic Center or globular clusters).
Numerical solutions for phase noise due to pointing jitter with the LISA telescope
激光干涉仪空间天线(LISA)的目的是通过航天器之间的长(2.5 Mkm)激光链路中的相位调制来探测引力波。要解决的其他噪声源包括由发射光束的可能角抖动引起的相位波动。本论文遵循我们的前一篇论文(Vinet et al 2019 Class.定量重力36,205 003)基于远场相位的分析研究。我们在这里解决的相位的数值处理,在发出的波前像差的第一顺序,但没有任何假设的静态偏置项。我们验证了,在相位变化,在静态错位的高阶项是一致的,我们在前面的文件中发现的结果。
Coupling of wavefront errors and pointing jitter in the LISA interferometer: misalignments of the interfering wavefronts
激光干涉仪空间天线是一种可预见的天基引力波探测器,其目标是在0.1 mHz至1 Hz的频率范围内探测10^20个应变。它是一个由三个航天器组成的三角形星座,边长为2.5 x 10^9米,每个航天器都有一对望远镜,可以同时发射和接收激光束,通过对接收到的波前与当地参考外差来测量星座臂。由于航天器和星座抖动,干扰(接收和本地)波前变得不对齐。我们研究分析失调和像差的干扰波前之间的耦合,并估计相关的外差信号的噪声的贡献。
