OVERVIEW

The course aims to provide a phenomenological introduction to modern astrophysics and cosmology in particular by showing the application to the context of the phenomena of the cosmos of different branches of classical and modern physics, in order to constitute a solid basis for students interested in a career in these disciplines, while providing knowledge of phenomena and methods for students interested in pursuing other areas of physics.

AIMS AND CONTENT

LEARNING OUTCOMES

Broad knowledge of the most important phenomena of astrophysics and cosmology

AIMS AND LEARNING OUTCOMES

At the end of the course the student will have knowledge regarding: units of measurement and observables in use; mechanisms of production of electromagnetic waves of different energies in astrophysical phenomena; interaction and propagation of photons in the cosmos and their detection (with hints to other messengers); elements of observational astronomy; stellar physics (equilibrium and various phases of stellar evolution, multiple systems); planetary systems; interstellar medium; extra-galactic astrophysics; elements of general relativity and cosmology for the description of the evolution of the universe on a large scale. The students will acquire an understanding of the different astrophysical phenomena by applying the knowledge of the various branches of classical and modern physics (classical mechanics, thermodynamics, electromagnetism, optics, relativity, quantum mechanics, statistical physics, nuclear physics, particle physics) and will be informed on the lines of leading research of modern astrophysics and cosmology.

TEACHING METHODS

Classes with use of the black board and of slides (given in advance)
