Abstract: U14.00008 : The Gravitational Compass: new space-based detection methods for circularly polarized gravitational waves
4:54 PM–5:06 PM
Preview Abstract Abstract
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.
