Galaxies and Cosmology

This course deals with the properties of galaxies, the large scale distribution of matter in the Universe, and the evolution of cosmic structures from the early cosmos until today. We introduce some fundamental theoretical concepts and contrast them with the available observational evidence. We will deal with the following topics: the standard model of cosmology; cosmological parameters and their determination; the early universe; formation and structure of galaxies; observations of galaxies; gas in galaxies and the local environment. Regular homework exercises will be reviewed in the bi-weekly exercise sessions. These exercises serve also to prepare for the written exam at the end of the semester.
