On the concordance of cosmological data in the case of the generalized Chaplygin gas
Ralf Aurich, Sven Lustig
The generalized Chaplygin gas cosmology provides a prime example for the class of unified dark matter models, which substitute the two dark components of the standard cosmological…
Early-Matter-Like Dark Energy and the Cosmic Microwave Background
Ralf Aurich, Sven Lustig
Early-matter-like dark energy is defined as a dark energy component whose equation of state approaches that of cold dark matter (CDM) at early times. Such a component is an ingredi…
The Hantzsche-Wendt Manifold in Cosmic Topology
Ralf Aurich, Sven Lustig
The Hantzsche-Wendt space is one of the 17 multiply connected spaces of the three-dimensional Euclidean space E^3. It is a compact and orientable manifold which can serve as a mode…
A search for cosmic topology in the final WMAP data
Ralf Aurich, Sven Lustig
A search for matched circle pairs of similar temperature fluctuations in the final WMAP 9yr data is carried out. Such a signature is expected if the space of the Universe is multip…
Cosmic Topology of Polyhedral Double-Action Manifolds
Ralf Aurich, Sven Lustig
A special class of non-trivial topologies of the spherical space S^3 is investigated with respect to their cosmic microwave background (CMB) anisotropies. The observed correlations…
Cosmic Topology of Prism Double-Action Manifolds
Ralf Aurich, Sven Lustig
The cosmic microwave background (CMB) anisotropies in spherical 3-spaces with a non-trivial topology are studied. This paper discusses the special class of the so-called double-act…
