Galaxies

Instructor: Jeremy Heyl

Wiki Destinations

Topics

Topics we will cover include:

  • Properties of normal galaxies,
  • Elements of stellar dynamics;
  • Galactic structure, dynamics and evolution;
  • Active galaxies and quasars;
  • Large scale structures.

Grading Scheme

I will base the grades on the homework assignments (40%, four percent each, drop the lowest mark), midterm (10%) and the final exam (50%).

Textbook

The required textbook is Galaxies in the Universe by Linda S. Sparke and John S. Gallagher, III. It is available on Amazon for $114.95 (new) (less for used) and at the UBC bookstore.
