Lecture 8: Normal galaxies to quasars

Further reading

• The American Institute of Physics has an excellent website called "Cosmic Journey: A History of Scientific Cosmology" at http://www.aip.org/history/cosmology/index.htm. The page called "Island Universes" discusses the discovery of galaxies in lots of detail.
• There's a good description of the different types of active galaxies at "Astronomy 162: Stars, Galaxies, and Cosmology" http://csep10.phys.utk.edu/astr162/lect/active/active.html
• There's another nice page at "Gene Smith's Astronomy Tutorial: Quasars and Active Galaxies" http://casswww.ucsd.edu/archive/public/tutorial/Quasars.html. This has lots of good information about the different types of active galaxies.
