Limits on the Detectability of Cosmic Topology in Hyperbolic Universes
G. I. Gomero, M. J. Reboucas, R. Tavakol
We reexamine the possibility of the detection of the cosmic topology in nearly flat hyperbolic Friedmann-Lemaitre-Robertson-Walker (FLRW) universes by using patterns repetition. We…
Detectability of Cosmic Topology in Flat Universes
G. I. Gomero, M. J. Reboucas
Recent observations seem to indicate that we live in a universe whose spatial sections are nearly or exactly flat. Motivated by this we study the problem of observational detection…
Are Small Hyperbolic Universes Observationally Detectable?
G. I. Gomero, M. J. Reboucas, R. Tavakol
Using recent observational constraints on cosmological density parameters, together with recent mathematical results concerning small volume hyperbolic manifolds, we argue that, by…
Signature for the Shape of the Universe
G. I. Gomero, M. J. Reboucas, A. F. F. Teixeira
If the universe has a nontrivial shape (topology) the sky may show multiple correlated images of cosmic objects. These correlations can be couched in terms of distance correlations…
Detectability of Cosmic Topology in Almost Flat Universes
G. I. Gomero, M. J. Reboucas, R. Tavakol
Recent observations suggest that the ratio of the total density to the critical density of the universe, , is likely to be very close to one, with a significant proportion of…
A Topological Signature in Cosmic Topology
G. I. Gomero, M. J. Reboucas, A. F. F. Teixeira
Two procedures for obtaining (extracting and constructing) the topological signature of any multiply connected Robertson-Walker (RW) universe are presented. It is shown through com…
