In this paper, the cosmic microwave background (CMB) anisotropy in a multiply connected compact flat 3-torus model with the cosmological constant is investigated. Using the COBE-DMR four-year data, a full Bayesian analysis revealed that the constraint on the topology of the flat 3-torus model with low matter density is less stringent. As in compact hyperbolic models, the large-angle temperature fluctuations can be produced as the gravitational potential decays at the Λ-dominant epoch well after…

Do we live in a ‘small universe’?
We compute the effects of a compact flat universe on the angular correlation function, the angular power spectrum, the circles-in-the-sky signature, and the covariance matrix of the spherical…
Detecting topology in a nearly flat spherical universe
When the density parameter is close to unity, the universe has a large curvature radius independent of its being hyperbolic or spherical, or in the limiting case of an infinite curvature radius,…

Microwave background anisotropy in a toroidal universe.
TLDR
Large-scale cosmic microwave background temperature fluctuations are calculated for a universe with the topology of a 3-torus and it is found that a topologically ``small'' universe is no longer an interesting cosmological model.

TLDR
The angular power spectrum of the cosmic microwave background, measured during the North American test flight of the Boomerang experiment, is used to constrain the geometry of the universe and new constraints on the fractional matter density and the cosmological constant are obtained.
