The ?eld of cosmology is currently undergoing a revolution driven by d- matic observational progress and by novel theoretical scenarios imported from particle physics. In particular, two most remarkable results were recently - tained from measurements of the angular spectrum of the ?uctuations in the Cosmic Microwave Background (CMB) radiation providing convincing e- dence that the Universe is nearly ?at and from the Hubble diagram of distant supernovae indicating an accelerating expansion rate, which implies the ex- tence of some dark energy as the dominant component of the Universe. Indeed, the next decade will bene't from high quality data on cosmology from diff- ent major experiments and observatories, with a particular important contri- tion from space missions such as WMAP, Planck Surveyor, XMM and SNAP among others.

The lectures published here provide graduate students and researchers with a survey of CMB radiation and an understanding of research in this field. The lectures cover the anisotropy, spectrum and polarization of the CMB from both observational and theoretical viewpoints. The importance of the CMB is discussed in lectures on general relativity, inflation, structure formation, nucleosynthesis and primordial molecules. There is detailed coverage of statistical and data analysis techniques that are useful in CMB research.
