The Gravitational Compass: New Space-Based Detection Methods For Circularly Polarized Gravitational Waves
Bulletin Of The American Physical Society
We investigate the sensitivity of space-based gravitational wave observatories based on the platonic solids -- tetrahedron, cube and octohedron -- to a circular polarization of an isotropic stochastic gravitational wave background (ISGWB) as a function of frequency. For such a detector geometry, each vertex is a drag-free satellite and each edge is a laser interferometer arm. Extrapolating the noise model from LISA to these new geometries, we find that these designs can lead to an increase in sensitivity to an ISGWB.
