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…

Reproducing the observed Cosmic microwave background anisotropies with causal scaling seeds
R. Durrer, M. Kunz, A. Melchiorri
During the last years it has become clear that global O(N) defects and U(1) cosmic strings do not lead to the pronounced first acoustic peak in the power spectrum of anisotropies o…

Cosmic Microwave Background Anisotropies from Scaling Seeds: Global Defect Models
Ruth Durrer, Martin Kunz, Alessandro Melchiorri
We investigate the global texture model of structure formation in cosmogonies with non-zero cosmological constant for different values of the Hubble parameter. We find that the abs…
