Winner of the 1999 Henry Norris Russell Lectureship, American Astronomical Society Jeremiah P. Ostriker, Co-Winner of the 2015 Gruber Cosmology Prize for Theoretical and Experimental Explorations of the Universe (with John Carlstrom and Lyman Page), The Gruber Foundation "As this lively volume attests, there are still many exciting problems left to interest the graduate student entering the field of astrophysics."--Wendy Freedman, Nature "On finishing the last chapter, I thought about what fun I could have teaching a special topics astrophysics course using this book. Who would learn more, the graduate students or the teacher?"--Physics Today
