Galaxies in the Universe by Sparke and Gallagher
An Introduction to Modern Cosmology by Liddle
Note both books have substantial errata, which are listed on the web pages
for the books.
An Introduction to Modern Astrophysics, by Carroll & Ostlie. We will refer
to the "big orange book" for some background reading.
Galactic Astronomy by Binney & Merrifield (1998) and the previous
edition by Mihalas & Binney (1981). This is the classic graduate
text in the field.
Modern Cosmology by Dodelson. Graduate level book on cosmology.
Galaxies and Galactic Structure by Elmegreen. This is an undergraduate text at a somewhat lower level than Sparke & Gallagher but covers some topics that Sparke & Gallagher doesn't.
Modern Cosmological Observations and Problems by Bothun. Somewhat out of date, but presents a nice overview of observational cosmology.
These books, along with the required texts will be
on reserve in the Science Library.
