Course slides provided by the teacher which include all the material presented during classesDan Maoz: Astrophysics in a Nutshell
Skills acquired (at the end of the course):
At the end of the course the student will have a basic knowledge of astrophysical objects with a comprehension of the main physical processes, especially in relation with stars, galaxies, active nuclei and galaxy clusters. Moreover, the student will have acquired a basic knowledge of the standard cosmological model, comprehending the basic hypotheses and their physical consequences. The student should then be able to apply his/her knowledge to build simple physical models of the astrophysical sources.
Courses required: Mathematical Analysis II, Physics I, Fluids, Thermodynamics/Statistics
Total hours of the course (including the time spent in attending lectures, seminars, private study, examinations, etc...): 150

Oral exam. The student will be asked to present a few specific topics of the course program. The student will have to use an appropriate language, demonstrating his/her comprehension of the main physical processes and of the consequences of the starting assumptions. More specific questions might be asked to better assess the student's comprehension level. The student will have to be able to perform simple order-of-magnitude calculations but also to develop the mathematical model, if this has been presented during classes.
