Conoscenze e abilità da conseguire

At the end of the course, the student will have the basic knowledge of the modern cosmology, based on the General Relativity and on the Hot Big Bang model. In particular the student knows in critical way: the assumptions underlying the Big Bang model and their consequences; the thermal history of universe and the corresponding epochs; the model of inflation; the theory of formation of cosmic structures. Finally the student will be able to present and discuss in critical way the constraints coming from observational data.

Metodi didattici

Lectures including discussions of related problems.

Modalità di verifica e valutazione dell'apprendimento

Oral exam. The aim of the interview is to verify that the student has the basic knowledge of modern cosmology and that he/she can discuss in a critical way the properties of the various cosmological models and their comparison with present observational data.

The exam starts from a topic chosen by the student, this will be followed by some more detailed discussion on the same topic and questions on other topics covered in the course.

Strumenti a supporto della didattica
