Cosmic topology. Part IIb. Eigenmodes, correlation matrices, and detectability of non-orientable Euclidean manifolds

Craig J. Copi, Amirhossein Samandar, Glenn D. Starkman +13

If the Universe has non-trivial spatial topology, observables depend on both the parameters of the spatial manifold and the position and orientation of the observer. In infinite Eu…

Cosmic topology. Part IIIb. Eigenmodes and correlation matrices of spin-2 perturbations in orientable Euclidean manifolds

Amirhossein Samandar, Javier Carrón Duque, Craig J. Copi +13

We study the eigenmodes of the spin-2 Laplacian in orientable Euclidean manifolds and their implications for the tensor-induced part of the cosmic microwave background (CMB) temper…

Gravitational Wave Scattering From the Sun and Planets

Daniel A. Kessler, Craig J. Copi, Glenn D. Starkman

General relativity predicts that massless waves should scatter from the Riemann curvature of their backgrounds. These scattered waves are sometimes called tails and have…
