Detectability of nontrivial topologies
Detectability of nontrivial topologies
We study how the uncertainty in the cosmological parameters impacts on the detection of topological signals, focussing on three cubic torus universes and using three tests: the information content, the $S/N$ statistic, and the Bayesian evidence. We find, within the concordance cosmological model, that 3D torus universes with a size …
