The majority of work will be project-based, each project conceived and built by the students from equipment available in the lab.

**Note**: While this is a three (3) credit hour course, it will be taught over two semesters.

**4600 High-Energy Astrophysics**3 credit hours

Prerequisite: ASTR 2400, PHYS 2400, PHYS 3300.

This course discusses the astrophysical processes that create high-energy photons (x-rays and gamma-rays) as well as the emission created from very energetic electrons (synchrotron and inverse Compton). Topics include gas and radiative processes, high-energy detectors and telescopes, and astrophysical processes from the solar system to black holes and gamma-ray bursts responsible for high-energy emission.

**4790 Research Thesis**6 credit hours

Prerequisite: honours standing.

A research project carried out by the student under the supervision of a faculty member in the Department throughout the Honours year. The project should be in the area of astrophysics for students in the honours astrophysics program. Results are written up in a formal thesis that adheres to standard University-set guidelines.

Directed study 3 hrs. per week; 2 semesters.

**4826 – 4849 Special Topics in Physics**3 credit hours

Prerequisite: permission of instructor

**4876 – 4899 Directed Study in Physics**3 credit hours
