The aim of this course, in brief, is to provide a broad introduction to extragalactic astrophysics and cosmology. Topics will include the Milky Way and normal galaxies, supermassive black holes, active galaxies, clusters of galaxies, and cosmology and the origin of structure in the Universe.

Lectures will be at 11:00am Tuesday and Thursday in room DUANE G131. My office is A909 (in the JILA tower) - feel free to stop by anytime with queries / problems / suggestions. Policies and further info about the course are set out in the course syllabus (pdf format). Problem sets will be posted here.

MIDTERM: Thursday March 8th in class

FINAL: Wednesday May 9th at 4:30pm


Problem set #1

Problem set #2
