Do we Live in a "Small Universe"?
Ralf Aurich, Holger S. Janzer, Sven Lustig +1
We compute the effects of a compact flat universe on the angular correlation function, the angular power spectrum, the circles-in-the-sky signature, and the covariance matrix of th…
CMB Alignment in Multi-Connected Universes
R. Aurich, S. Lustig, F. Steiner +1
The low multipoles of the cosmic microwave background (CMB) anisotropy possess some strange properties like the alignment of the quadrupole and the octopole, and the extreme planar…
The circles-in-the-sky signature for three spherical universes
R. Aurich, S. Lustig, F. Steiner
The mysteriously low CMB power on the largest scales might point to a Universe which consists of a multi-connected space. In addition to a suppression of large-scale power, a multi…
Can one hear the shape of the Universe?
R. Aurich, S. Lustig, F. Steiner +1
It is shown that the recent observations of NASA's explorer mission "Wilkinson Microwave Anisotropy Probe" (WMAP) hint that our Universe may possess a non-trivial topology. As an e…
CMB Anisotropy of the Poincare Dodecahedron
R. Aurich, S. Lustig, F. Steiner
We analyse the anisotropy of the cosmic microwave background (CMB) for the Poincare dodecahedron which is an example for a multi-connected spherical universe. We compare the temper…
Hyperbolic Universes with a Horned Topology and the CMB Anisotropy
Ralf Aurich, Sven Lustig, Frank Steiner +1
We analyse the anisotropy of the cosmic microwave background (CMB) in hyperbolic universes possessing a non-trivial topology with a fundamental cell having an infinitely long horn.…
