Introduction to High-Energy Astrophysics

Stephan Rosswog, Marcus Brüggen,
Cambridge University Press, Sept. 2007

  • "... it makes an easy transition to the applications of physics to astrophysics ... The book is well constructed and develops derivations and explanations that are presented in logical sequences of thought with an ease characteristic of few books of its kind ... This is an excellent choice for the bookshelves of current and aspiring astrophysicists ... Summing Up: Highly recommended." Choice Reviews Online
  • "It could easily form the basis of more than one undergraduate course and should be required reading for anyone working in high-energy astrophysics. The style and layout are clear and all for a reasonable price. Highly recommended." The Observatory
  • "...this book contains everything a beginner in this topic needs to know: special relativity, gas and radiation processes, neutron stars, X-ray binaries, supernovae, active galactic nuclei, even gamma-ray bursts are covered in detail in an extra-chapter. ...The text is written in a very coherent way, physics equations are explicitely derived, physics students will appreciate that. ...a pedagogically well-thought-out text book. It is highly recommended to all physics students that want to engage in high-energy astrophysics." Sterne und Weltraum.
