The variance of the CMB temperature gradient: a new signature of a multiply connected Universe
Ralf Aurich, Thomas Buchert, Martin J. France +1
In this work we investigate the standard deviation of the Cosmic Microwave Background (CMB) temperature gradient field as a signature for a multiply connected nature of the Univers…
Model-independent analyses of non-Gaussianity in Planck CMB maps using Minkowski Functionals
Thomas Buchert, Martin J. France, Frank Steiner
Despite the wealth of results, there are difficulties in disentangling the primordial non-Gaussianity of the Cosmic Microwave Background (CMB) from the secondary and the f…
Evidence for an environment-dependent shift in the baryon acoustic oscillation peak
Boudewijn F. Roukema, Thomas Buchert, Jan J. Ostrowski +1
The Friedmann-Lemaitre-Robertson-Walker (FLRW) metric assumes comoving spatial rigidity of metrical properties. The curvature term in comoving coordinates is environment-independen…
Deep redshift topological lensing: strategies for the T^3 candidate
Boudewijn F. Roukema, Martin J. France, Tomasz A. Kazimierczak +1
The 3-torus (T^3) FLRW model better fits the nearly zero large-scale auto-correlation of the WMAP CMB sky maps than the infinite flat model. The T^3 model's WMAP parameters imply a…
