Cosmic Strings, Inflation and the Cosmic Microwave Background

Theories of physics beyond the Standard Model predict the existence of relativistic strings, either as composite objects, or as fundamental constituents of matter. In a class of well-motivated models of the early Universe, inflation ends by producing cosmic strings, which will still be present at a low density today. This talk reviews the status of cosmic strings in inflationary cosmology, and describes the latest constraints from the Cosmic Microwave Background data.
