Course Description

This course is a survey of the emerging field of high-energy particle astrophysics and is primarily intended for students pursuing a master’s degree in physics. Phenomena studied in this field are among the most energetic in Universe and include the theory and observation of particles accelerated in supernovae remnants, super-massive black holes, active galaxies, and gamma ray bursts.

This course will feature an emphasis on problem solving using numerical techniques. Although certainly is not a requirement to understand the physical processed involved in astroparticle phenomena, it is benefitial to resolve numerically some of the proposed problems in order to better assimilate the concepts discussed during this course. The Python programming language is used as a tool for constructing these numerical solutions. There exist complete mathematical libraries (NumPy/SciPy) for Python as well as powerful interactive tools and graphical visualization frameworks which make it possible to easily construct problem solvers in a matter of minutes along with graphical output. as the programing language. The idea is also to familiarize the student with what has become one of the most popular analysis tools in the high energy physics as well as astronomy communities.

The course nominally includes 24 hours of lecture and 24 hours of exercises. These hours will be divided (approximately) among 7 lectures, 7 exercise sessions. In addition, you will be asked to select a topic to pursue for individual in-depth analysis. This could involve selecting a paper for review, critique, and presentation or could be modeling an astrophysical phenomenon in code followed by a presentation of the work. The possibilities are open, however you must work with me to develop a topic. Presentations and work must be completed by the end of the quadrimester.

There is no mandatory textbook for this course. However, the students are encouraged to enrich their instruction by reviewing external references. There is a great wealth of high-quality information freely available on the internet, in particular the “arXiv” preprint server at http://arxiv.org. There the student can search for and download articles and reviews of the astroparticle subject. Some useful reviews are:

Also to note is the Particle Data Group website (http://pdg.lbl.gov) which hosts the Reviews of Particle Physics 20XX itself a compendium of tabulated information useful for particle physicists as well as reviews on topics from the passage of radiation through matter to Big-Bang cosmology.

Material for the course has been variously taken from the following textbooks:

  1. Gaisser, T.K. Cosmic Rays and Particle Physics, Cambridge University Press, 1991
  2. Longair, M. High-Energy Astrophysics Volume 1: Particles, photons, and their detection, Cambridge University Press, 2004
  3. Perkins, D. Particle Astrophysics, Oxford University Press, 2008

Grading

45% of the grade will be based on the student project. The other 45% will derive from the final written exam. The exam will consist on exercises (similar to those seen during the course) and theoretical questions. All material will be allowed during the written exam. The rest of 10% will come from participation and doing the exercises.
