A new analysis of Poincaré dodecahedral space model
S. Caillerie, M. Lachièze-Rey, J. -P. Luminet +3
The full three-year WMAP results (WMAP3) reinforce the absence of large-angle correlations at scales greater than 60 degrees. The Poincare dodecahedral space (PDS) model model, whi…
On the detectability of non-trivial topologies
M. Kunz, N. Aghanim, A. Riazuelo +1
We explore the main physical processes which potentially affect the topological signal in the Cosmic Microwave Background (CMB) for a range of toroidal universes. We consider speci…
Tracking quintessence by cosmic shear - Constraints from VIRMOS-Descart and CFHTLS and future prospects
Carlo Schimd, Ismael Tereno, Jean-Philippe Uzan +6
Dark energy can be investigated in two complementary ways, by considering either general parameterizations or physically well-defined models. Following the second route, we explore…
Constraining Cosmic Topology with CMB Polarization
Alain Riazuelo, Samuel Caillerie, Marc Lachièze-Rey +2
Multiply connected space sections of the universe on a scale smaller than the horizon size can leave an imprint on cosmic microwave background polarization maps, in such a way that…
Cosmic microwave background multipole alignments in slab topologies
James G. Cresswell, Andrew R. Liddle, Pia Mukherjee +1
Several analyses of the microwave sky maps from the Wilkinson Microwave Anisotropy Probe (WMAP) have drawn attention to alignments amongst the low-order multipoles. Amongst the var…
Constraining topology in harmonic space
M. Kunz, N. Aghanim, L. Cayon +3
We consider several ways to test for topology directly in harmonic space by comparing the measured a_lm with the expected correlation matrices. Two tests are of a frequentist natur…
