12 High Energy Astrophysics 2017

Objectives

Students should become familiar with the basics of High Energy Astrophysics, not only with respect to the sources and astrophysical processes that produce X rays, gamma rays and cosmic rays in our universe, but also with the instruments that detect these photons / particles. The course is divided into three blocks. The first part is a theoretical description of the main processes of interaction of matter and radiation in the X- and gamma-ray energy domain. The second one describes the detectors that are currently operating, those under construction and those being designed. The third and final block presents the phenomenology of several cosmic sources of X rays, gamma rays, cosmic rays that have been observed so far.

Skills

  • Formulate and tackle problems, both open and more defined, identifying the most relevant principles and using approaches where necessary to reach a solution, which should be presented with an explanation of the suppositions and approaches.
  • Understand the bases of advanced topics selected at the frontier of high energy physics, astrophysics and cosmology and apply them consistently.

Learning outcomes

  1. Analyze the different sources of cosmic radiation.
  2. Understand the physical processes responsible for the emission, propagation and absorption of cosmic radiation (charged particles, photons and neutrinos).
