The Master’s Degree Programme in Astronomy and Astrophysics has a two-year duration and awards 120 ECTS. Admission to this programme is not restricted and takes place by means of the assessment of the student’s curricular requisites and personal skills.
The learning outcomes of the Master’s Degree Programme in Astronomy and Astrophysics depend on the relating class (LM-58, Science of the Universe).
Masters graduates in Astronomy and Astrophysics have achieved the following learning outcomes:
• a mastery of the scientific research method, based on a sound background in classical and modern physics and the necessary expertise in the use of mathematical methodologies and IT tools;
• an excellent knowledge of modern astronomy and astrophysics, with wide scientific, operational, observation and theoretical skills in the issues relating to the class;
• advanced skills in modern instrumentation and observation techniques, in the data collection and analysis procedures as well as in model building.
Thanks to this degree programme, masters graduates can be admitted to PhD schools, 2nd level professional masters and can hold technical and managerial duties in Civil Service and in the private sector.
In particular, masters graduates may become laboratory technicians, scientific programmers, data analysts, software developers for scientific and industrial applications, commercial technicians for customer support (for example, in case of instrumentation manufacturers). By taking advantage of their cross-curricular mathematical and technical skills, masters graduates may successfully cooperate with other professionals such as engineers, managers and IT specialists.
To be admitted to the master’s degree programme in Astronomy and Astrophysics, students must hold a bachelor’s degree, a three-year academic diploma or any other suitable title of study got abroad and deemed as equivalent by the University.
Students must have a good knowledge of classical and modern physics, elements of chemistry and of the required mathematics and computer science tools. They are required to have a good command of Italian, both oral and written. They must also be able to effectively use English, both oral and written, in their specific framework and for the exchange of general information (B-1 level according to the QCER, Quadro comune europeo diriferimento per la conoscenza delle lingue, Common European Framework of Reference for Languages).
To be admitted to the master’s degree programme, bachelor’s graduates must have
acquired at least:
overall 20 ECTS in mathematics and/or computer science disciplines (MAT/01-MAT/08,
INF/01 and ING-INF/05);
5 ECTS in chemistry disciplines (CHIM/01-03 and CHIM/06);
65 ECTS in physics disciplines (FIS/01-FIS/08), out of which at least 40 ECTS in
experimental physics (FIS/01), 12 ECTS in theoretical physics, mathematical models and

A fundamental pre-requisite is that students must have the knowledge requested by the first level University degree in Physics or in Astronomy and Astrophysics. Specific competences are requested in classical physics, quantum mechanics, atomic and molecular processes, nuclear physics. It is important that students have basic knowledge of astronomy (measurements of distance, mass, and luminosity, photometric and spectroscopic observational techniques), astrophysics (fundamental evolutionary phases of the Universe, general properties of stars and galaxies, the most important radiative processes in astrophysics), and in the theory of weak interactions.
