The variance of the CMB temperature gradient: a dependence on the spatial orientation and anisotropy of a multiply connected Universe
Ralf Aurich, Martin J France, Frank Steiner
In the present work we develop a model--independent method to reveal the underlying patterns of anisotropy and geometry in CMB temperature maps. This method, based on the rho-stati…

A spatial-correlation analysis of the cubic 3-torus topology based on the Planck 2013 data
R. Aurich
Spatial correlations of the cubic 3-torus topology are analysed using the Planck 2013 data. The spatial-correlation method for detecting multiply connected spaces is based on the f…

The Cosmic Microwave Background for a Nearly Flat Compact Hyperbolic Universe
R. Aurich, F. Steiner
The fluctuations of the cosmic microwave background (CMB) are investigated for a hyperbolic universe with finite volume. Four-component models with radiation, matter, vacuum energy…
