Tools of Radio Astronomy

By: T. L. Wilson,Kristen Rohlfs,Susanne Hüttemeister

Four signi?cant factors have led us to update this text. The ?rst is the breathtaking progress in technology, especially in receiver and digital techniques. The second is the advance of radio astronomy to shorter wavelengths, and the increased availab- ity of astronomical satellites. The third is a need to reorganize some of the chapters in order to separate the basic theory, that seldom changes, from practical aspects that change often. Finally, it is our desire to enhance the text by including problem sets for each chapter. In view of this ambitious plan, we have expanded the number of authors. In the reorganization of this edition, we have divided Chap. 4 of the 4th edition into two Chaps. 4 and 5. The ?rst remains Chap. 4, with a slightly different - tle, Signal Processing and Receivers: Theory. This was expanded to include digital processing and components including samplers and digitizers. In Chap. 5, Prac- cal Receiver Systems. we have relegated the presentations of maser and parametric ampli?er front ends, which are no longer commonly used as microwave receivers in radio astronomy, to a short section on “historical developments” and We have retained and improved the presentations of current state-of-the-art devices, cooled transistor and superconducting front ends. We have also included descriptions of local oscillators and phase lock loops. Chapters 5 and 6 in the 4th edition has now become Chap. 6, Fundamentals of Antenna Theory and Chap.

Tools of Radio Astronomy

By: Kristen Rohlfs,T. L. Wilson

1. Most authoritative and established of graduate-level textbooks and references in the field. 2. Provides not only specialists with the details they need but also non-specialists with access to the jargon and basics of this vital field. 3. New edition offers completely rewritten chaptes on interferometry and aperture synthsis, as well as thoroughly revised chapters on receiver technology and interstellar molecules. 4. From the reviews of previous editions: "Nowadays Rohlfs and Wilson`s Tools of Radio Astronomy is the inevitable reference book. This is the one book you should buy if you want to become a radio astronomer. " The Observatory, 2001 "An excellent survey of the tools a radio astronomer needs to pursue the trade... The neatly encapsulated derivations of many classical relations will make the book useful to lecturer and student and practicing astronomer alike." American Scientist "People use this book so much because it describes what one needs in order to actually do radio astronomy... This book is an excellent graduate level text - the best available by far. It is also the best reference book for practicing astronomers who want to do radio astronomy properly, to interpret jargon or to understand some of the details of the literature." Physics Today

Tools of Radio Astronomy

By: Thomas L. Wilson,Kristen Rohlfs,Susanne Hüttemeister

This 6th edition of “Tools of Radio Astronomy”, the most used introductory text in radio astronomy, has been revised to reflect the current state of this important branch of astronomy. This includes the use of satellites, low radio frequencies, the millimeter/sub-mm universe, the Cosmic Microwave Background and the increased importance of mm/sub-mm dust emission. Several derivations and presentations of technical aspects of radio astronomy and receivers, such as receiver noise, the Hertz dipole and beam forming have been updated, expanded, re-worked or complemented by alternative derivations. These reflect advances in technology. The wider bandwidths of the Jansky-VLA and long wave arrays such as LOFAR and mm/sub-mm arrays such as ALMA required an expansion of the discussion of interferometers and aperture synthesis. Developments in data reduction algorithms have been included. As a result of the large amount of data collected in the past 20 years, the discussion of solar system radio astronomy, dust emission, and radio supernovae has been revisited. The chapters on spectral line emission have been updated to cover measurements of the neutral hydrogen radiation from the early universe as well as measurements with new facilities. Similarly the discussion of molecules in interstellar space has been expanded to include the molecular and dust emission from protostars and very cold regions. Several worked examples have been added in the areas of fundamental physics, such as pulsars. Both students and practicing astronomers will appreciate this new up-to-date edition of Tools of Radio Astronomy.
