The Role of Topological Defects in Cosmology

Topological defects are involved in a plethora of physical and astrophysical phenomena. In these lectures, I will review the rôle they could play in the large-scale structure formation and the anisotropies of the cosmic microwave background, as well as in various high energy phenomena, including baryon number asymmetry, ultra-high energy cosmic rays, and gamma ray bursts. I will then summarize ...

Bottom-up vs. Top-down Scenarii 1

We present an overview on extreme energy cosmic rays (EECR) and the fundamental physics connected with them. The top-down and bottom-up scenarii are contrasted. We summarize the essential features underlying the top-down scenarii for EECR, namely, the lifetime and the mass imposed to the heavy relics whatever they be: topological and non-topological solitons, X-particles, cosmic defects, micros...

Cosmic Strings and Cosmic Supertrings

In these lectures, I review the current status of cosmic strings and cosmic superstrings. I first discuss topological defects in the context of Grand Unified Theories, focusing in particular in cosmic strings arising as gauge theory solitons. I discuss the reconciliation between cosmic strings and cosmological inflation, I review cosmic strings dynamics, cosmic string thermodynamics and cosmic ...

Topological Defects and Structure Formation ⋆

Topological defects are produced during phase transitions in the very early Universe. They arise in most unified theories of strong, weak and electromagnetic interactions. These lectures focus on the role of topological defects in cosmology, with particular emphasis on the models of structure formation based on defects. The role of topological defects in baryogenesis is also reviewed. ⋆ Based o...
