(Topological) defects and the CMB

This talk will be a pedagogical introduction to different types of topological and non-topological defects, how they arise in high-energy physics and what properties they have. The more technical question of how to simulate them in the computer will be then tackled in order to obtain CMB power spectra. Once the spectra are obtained, the newest CMB constraints for defects will be discussed.
