Conoscenze e abilità da conseguire
At the end of the course, the student will acquire the basic knowledge of the theory of gravitational lensing, and will be able to discuss the applications of lensing in different astrophysical branches. In particular, the student will be able to distinguish between different regimes of lensing (strong, weak, etc) and will learn through examples how to carry out lensing analyses. The basics of the Python programming language will also be taught to allow the students to better understand the examples and work on small projects.
