Lecture 7: The Milky Way

Further reading

• The website of the UCLA Galactic Centre group is at http://www.astro.ucla.edu/~ghezgroup/gc/index.shtml. It contains lots of interesting pictures and animations about the great work they are doing.
• Scientific American had a cover story devoted to dark matter in November 2010: "Dark Worlds" by Jonathan Feng and Mark Trodden. It does a very good job of explaining the various candidates for dark matter and how experimenters are looking for them. There's a copy available at Jonathan Feng's website at http://www.ps.uci.edu/~jlf/research/press/dm_1011sciam.pdf
