Frontiers of the Universe: What do we know, what do we understand?
Ruth Durrer
In this talk I summarize the topics addressed during the conference. We have discussed the most relevant cosmological observations of the last say 10 years and their implications f…
Cosmological Strucure Formation with Topological Defects
Ruth Durrer
Structure formation with topological defects is described. The main differences from inflationary models are highlighted. The results are compared with recent observations. It is c…
An analytic approximation of MDM power spectra in four dimensional parameter space
B. Novosyadlyj, R. Durrer, V. N. Lukash
An accurate analytic approximation of the transfer function for the power spectra of primordial density perturbations in mixed dark matter models is presented. The fitting formula…
Signatures of Topological Defects in the Microwave Sky: An Introduction
Ruth Durrer
An introduction to topological defects in cosmology is given. We discuss their possible relevance for structure formation. Especial emphasis is given on the signature of topologica…
Global textures and the Doppler peaks
Alejandro Gangui, Ruth Durrer, Mairi Sakellariadou
We review recent work aimed at showing how global topological defects influence the shape of the angular power spectrum of the CMB radiation on small scales. While Sachs-Wolfe fluc…
