New: General Relativity (Lecture Notes) by Matthias Bartelmann

Einstein's theory of general relativity is still the valid theory of gravity, built upon simple principles and relating the geometry of space-time to its matter-energy content. These lecture notes by Matthias Bartelmann firstly introduce the reader to the underlying physical principles and the necessary mathematical tools taken from differential geometry. The subsequent discussion of cosmological models and black holes is concluded by two applications of general relativity to astrophysics.
