'Refreshingly, both the observational and theoretical aspects are discussed with equal competence, which, along with the many fine illustrations and diagrams, makes for an interesting read. The authors have done an excellent job of presenting a great deal of complex information succinctly. The test should be required reading for anyone involved in, or about to be involved in, research on AGN or quasars.' A. D. Andrews, Irish Astronomical Journal
'A quiet revolution has been occurring in the field of extragalactic astronomy … Following these strides in AGN research, new books that seek to summarize the state of current research are welcome. Ajit Kembhavi and Jayant Narlikar's Quasars and Active Galactic Nuclei is one such book … Within a historical background and cosmological framework, and with an easy-to-read style, the authors state their ideas clearly, introduce important physical and astronomical concepts, and explain their relevance to AGN … This book serves well as an introductory text for the advanced undergraduate or beginning graduate student who wishes general knowledge of the field of AGN research.' Physics Today
The latest observations and theoretical models are combined in this clear, pedagogic textbook for advanced undergraduates and graduate students. Throughout, theories and models are critically compared with observations. Topics include relativistic beaming, accretion disks, gravitational lensing and unification. Emphasis is placed on radio, X- and gamma-ray observations – not covered in any previous book.
