Goal of the course

The class is an introduction to the study of high-energy astrophysical systems. It will emphasize the derivation from actual observational data of (open and answered) research questions that have been and are being actively pursued by researchers in the field. The students are expected to participate in the development, in class, of simple models that can explain such observations. Our tools in this quest will be the special and general theories of relativity, some basic knowledge of particle physics, and non-thermal emission mechanisms. The (re)familiarization with these tools will frequently alternate with astrophysical applications.
