Learning objectives Referring to knowledge — Acquire a basic understanding of the structure, kinematics and dynamics of the Milky Way. — Advance in the knowledge of processes of formation and evolution of spiral galaxies. — Become familiar with the physical properties of the interstellar medium and of the stellar components of the Milky Way. — Understand which observables properties are available to us. Understand the precision in what can be attained today. — Acquire knowledge of statistical analysis techniques. Teaching blocks 1. Introduction 1.1. Galaxies and their place in the Universe 1.2.

Official assessment of learning outcomes Assignments proposed to students (optional) and oral presentation (15 minutes) in front of the class. Examination-based assessment Single assessment consists of a written examination to assess student progress. Repeat assessment criteria Repeat assessment takes place in June and consists of a written examination to assess the improvement in student progress. The final grade includes proposed assignments (optional) and oral presentations carried out by students throughout the course (20% of the final grade).
