'The third edition of Malcolm Longair's High Energy Astrophysics is a remarkable gem. It is written in the clear, lucid style that characterizes Professor Longair's monographs and displays an admirable balance between breadth and depth. It is remarkably up to date and covers both high-energy phenomenology and physical processes with authority. It would serve equally well as a textbook for a graduate-level course or a reference work for the practising astrophysicist: a nicely written and sophisticated appendix on basic astronomy will make it equally useful for readers trained as physicists.' Bradley M. Peterson, Professor and Chair of Astronomy, Ohio State University 'The remarkable revolution in our understanding of the Universe is covered brilliantly in this authoritative third edition of a classic text by Professor Longair - the prominent Cambridge astrophysicist and one of the subject's most experienced expositors. The text conveys the excitement of the progress being made in both observational and computational astronomy and ably describes the physical processes involved prior to educating the reader on a comprehensive list of frontier research topics ranging from dead stars in our Galaxy, black holes in galactic nuclei to the evolutionary history of galaxies seen at early cosmic times. The new edition is comprehensively illustrated and indexed with up-to-date references and an essential purchase for all physicists and astronomers.' Richard Ellis, Steele Professor of Astronomy, California Institute of Technology 'This is a great book for students and researchers alike. It is up to date and covers the exciting new developments in high energy astrophysics. It will be on my shelf at arm's reach.' Neil Gehrels, Chief, Astroparticle Physics Laboratory, NASA/GSFC and College Park Professor of Astronomy, University of Maryland 'The book is really a treasure for any student and teacher interested in astrophysics. It is very up to date and synoptically covers the whole field of high-energy astrophysics. I will use the book for my lectures as soon as I can!' Günther Hasinger, Scientific Director, Max-Planck-Institut für Plasmaphysik '… well-written and highly informative … stimulating and useful … beautifully written and authoritative … delivered with enthusiasm and offering the reader the chance to gain insight and understanding of a fascinating topic.' The Observatory '… a substantial textbook … likely to remain the standard on the subject for many years … comprehensive in its spread of subject matter and methodical in presentation.'
