Betti Functionals as a Probe for Cosmic Topology
Ralf Aurich, Frank Steiner
The question of the global topology of the Universe (cosmic topology) is still open. In the CDM concordance model it is assumed that the space of the Universe possesses the triv…
Hot pixel contamination in the CMB correlation function?
R. Aurich, S. Lustig, F. Steiner
Recently, it was suggested that the map-making procedure, which is applied to the time-ordered CMB data by the WMAP team, might be flawed by hot pixels. This could lead to a bias i…
Numerical computation of Maass waveforms and an application to cosmology
R. Aurich, F. Steiner, H. Then
We compute numerically eigenvalues and eigenfunctions of the Laplacian in a three-dimensional hyperbolic space. Applying the results to cosmology, we demonstrate that the methods l…
Quintessence and the Curvature of the Universe after WMAP
R. Aurich, F. Steiner
We study quintessence models with a constant (effective) equation of state. It is investigated whether such quintessence models are consistent with a negative spatial curvature of…
