| Objectives | |
|---|---|
| THIS TEACHING IS FOCUSED ON THE ROLE OF NUCLEAR AND PARTICLE PHYSICS IN ASTROPHYSICS STUDENTS WILL REACH A GOOD GENERAL KNOWLEDGE OF THE ROLE OF NUCLEAR AND PARTICLE PHYSICS PROCESSES IN ASTROPHYSICAL ENVIRONMENTS. THEY WILL LEARN THE EXPERIMENTAL TECHNIQUES USED TO DETERMINE NUCLEAR QUANTITIES OF ASTROPHYSICAL INTEREST AND THE PATH FROM ASTROPHYSICAL MODELS TO THE COMPARISON OF DATA, IN PARTICULAR THOSE FROM MULTI-MESSENGER ASTRONOMY. VARIOUS ASTROPHYSICAL OBSERVABLES WILL BE COMPUTED AND COMPARED WITH THE OBSERVED DATA FROM NEUTRINOS, COSMIC RAYS, PHOTONS, GRAVITATIONAL WAVES. EXPERIMENTAL APPARATUSES FOR MULTI-MESSENGER ASTRONOMY WILL BE DESCRIBED |
| Prerequisites | |
|---|---|
| THE COURSE REQUIRES A GOOD KNOWLEDGE OF QUANTUM MECHANICS AND OF THE EXPERIMENTAL TECHNIQUES IN NUCLEAR AND PARTICLE PHYSICS |

| Teaching Methods | |
|---|---|
| THE COURSE IS BASED ON LECTURES, TOTAL 48 HOURS. ATTENDING LECTURES IS NOT MANDATORY, BUT STRONGLY RECOMMENDED. TWO HOURS OF INDIVIDUAL STUDY FOR EACH HOUR OF LECTURE ARE ON AVERAGE NECESSARY TO FOLLOW THE COURSE WITH PROFIT. |
| Verification of learning | |
|---|---|
| THE ASSESSMENT OF THE COMPETENCE OF STUDENTS WILL BE BASED ON AN ORAL TEST. THE ORAL TEST WILL CONSIST IN AN INTERVIEW (APPROX. 60 MIN) ON THE CONTENTS OF THE COURSE PROGRAM. AN INDIVIDUAL STUDY ON A SUBJECT CHOSEN IN AGREEMENT WITH THE TEACHER WILL BE PART OF THE TEST. THIS STUDY WILL TYPICALLY BE FOCUSED ON THE ROLE OF NUCLEAR OR PARTICLE PHYSICS PROCESSES IN A SELECTED ASTROPHYSICAL SCENARIO, AND ON THE IMPACT OF THE THEORETICAL AND EXPERIMENTAL UNCERTAINTIES. A BASIC OVERALL KNOWLEDGE OF THE COURSE PROGRAM IS REQUIRED TO PASS THE EXAMINATION. THE MAXIMUM RATING (30 CUM LAUDE) REQUIRES THE ABILITY OF FACING CASES NOT EXPLICITLY INCLUDED IN THE PROGRAM, BUT FULLY APPROACHABLE WITH THE PROVIDED INFORMATION. |
