Virialization-induced curvature versus dark energy
Jan J. Ostrowski, Boudewijn F. Roukema, Thomas Buchert
The concordance model is successful in explaining numerous observable phenomena at the price of introducing an exotic source of unknown origin: dark energy. Dark energy dominance o…
Direct Minkowski Functional analysis of large redshift surveys: a new high--speed code tested on the luminous red galaxy Sloan Digital Sky Survey-DR7 catalogue
Alexander Wiegand, Thomas Buchert, Matthias Ostermann
As deeper galaxy catalogues are soon to come, it becomes even more importantto measure large-scale fluctuations in the catalogues with robust statistics that cover all moments of t…
Lagrangian theory of structure formation in relativistic cosmology II: average properties of a generic evolution model
Thomas Buchert, Charly Nayet, Alexander Wiegand
Kinematical and dynamical properties of a generic inhomogeneous cosmological model, spatially averaged with respect to free-falling (generalized fundamental) observers, are investi…
Virialisation-induced curvature as a physical explanation for dark energy
Boudewijn F. Roukema, Jan J. Ostrowski, Thomas Buchert
The geometry of the dark energy and cold dark matter dominated cosmological model (LambdaCDM) is commonly assumed to be given by a Friedmann-Lemaitre-Robertson-Walker (FLRW) metric…
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…
