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.

Radio astronomy uses unique observational techniques and offers the only way to investigate many phenomena in the Universe. This book, by two founders of the field, presents both a clear introduction to radio telescopes and techniques, and a broad overview of the radio universe. The material in this new edition has been expanded and updated, reflecting the developments in the field over the last decade. New material reflects the increasing use of aperture synthesis and Very Long Baseline Interferometry, and the further exploitation of molecular spectral lines. A new chapter is devoted to the fundamentals of radiation and propagation theory. The second half of the book constitutes a review of radio observations of our Milky Way galaxy. Wide-ranging and clearly written, this book provides a thorough and up-to-date introduction to the subject for graduate students, and an invaluable overview for researchers turning to radio astronomy for the first time.

Hidden from human view, accessible only to sensitive receivers attached to huge radio telescopes, giant versions of backyard satellite dishes, the invisible universe beyond our senses continues to fascinate and intrigue our imaginations. We cannot really comprehend what it means to say that a galaxy is exploding, yet that is the nature of some of the distant radio sources in the furthest reaches of space. Closer to home, in the Milky Way galaxy, radio astronomers listen patiently to the ticking of pulsars that tell of star death and states of matter of awesome densities. And between the stars, radio emission from a host of over 120 complex molecules radiate outward to reveal a tale about chemical processes that produce the very stuff of life. And all of this happens out there in the universe hidden from our eyes, even when aided by the Hubble Space Telescope. This is the story of radio astronomy, of how radio waves are generated by stars, supernova, quasars, colliding galaxies, and by the very beginnings of the universe itself. In The Invisible Universe, you learn what astronomers are doing with those huge dishes in the New Mexico desert, in a remote valley in Puerto Rico, in the green Pocahontas Valley in West Virginia, as well as dozens of other remote sites around the world. With each of these observatories, the scientists collect and analyze their data, "listening" to the radio signals from space, in order to learn what is out there, and perhaps even if someone else may be listening as well.

In the field of astrophysics, modern developments of practice are emerging in order to further understand the spectral information derived from cosmic sources. Radio telescopes are a current mode of practice used to observe these occurrences. Despite the various accommodations that this technology offers, physicists around the globe need a better understanding of the underlying physics and operational components of radio telescopes as well as an explanation of the cosmic objects that are being detected. Analyzing the Physics of Radio Telescopes and Radio Astronomy is an essential reference source that discusses the principles of the astronomical instruments involved in the construction of radio telescopes and the analysis of cosmic sources and celestial objects detected by this machinery. Featuring research on topics such as electromagnetic theory, antenna design, and geometrical optics, this book is ideally designed for astrophysicists, engineers, researchers, astronomers, students, and educators seeking coverage on the operational methods of radio telescopes and understanding the physical processes of radio astronomy.

Radio astronomy was born during the Second World War, but as this book explains, the history of early Dutch radio astronomy is in several respects rather anomalous in comparison to the development of radio astronomy in other countries. The author describes how these very differences led the Netherlands to become one of the world leaders in radio astronomy. Dominated by the Leiden astronomer Jan Hendrik Oort, the field embarked on an era of success, and to this day, the country still holds a leading position. To tell this story, the book focuses on three key events in the period 1940-1970, namely the construction of the radio telescopes in Kootwijk (1948), in Dwingeloo (1956), and in Westerbork (1970). These projects show that Dutch radio astronomers must not be seen as merely scientists, but also as strategic lobbyists, networkers and organizers in a specific political and economic context. It was in the process of planning, designing and constructing these instruments that the interests of the astronomers, industrial partners, politicians and lobby groups merged to create today's existing research centers for radio astronomy.

Radio astronomy is far from being beyond the scope of amateurs astronomers, and this practical, self-contained guide for the newcomer to practical radio astronomey is an ideal introduction. This guide is a must for anyone who wants to join the growing ranks of 21st Century backyard radio astronomers. The first part of the book provides background material and explains (in a non-mathematical way) our present knowledge of the stronger radio sources – those observable by amateurs – including the Sun, Jupiter, Meteors, Galactic and extra-galactic sources. The second part of the book deals not only with observing, but – assuming no prior technical knowledge of electronics or radio theory – takes the reader step-by-step through the process of building and using a backyard radio telescope. There are complete, detailed plans and construction information for a number of amateur radio telescopes, the simplest of which can be put together and working – using only simple tools – in a weekend. For other instruments, there are full details of circuit-board layouts, components to use and (vitally important in radio astronomy) how to construct antennae for radio astronomy.

How radio astronomers challenged national borders, disciplinary boundaries, and the constraints of vision to create an international scientific community. For more than three thousand years, the science of astronomy depended on visible light. In just the last sixty years, radio technology has fundamentally altered how astronomers see the universe. Combining the wartime innovation of radar and the established standards of traditional optical telescopes, the “radio telescope” offered humanity a new vision of the universe. In A Single Sky, the historian David Munns explains how the idea of the radio telescope emerged from a new scientific community uniting the power of radio with the international aspirations of the discipline of astronomy. The radio astronomers challenged Cold War era rivalries by forging a united scientific community looking at a single sky. Munns tells the interconnecting stories of Australian, British, Dutch, and American radio astronomers, all seeking to learn how to see the universe by means of radio. Jointly, this international array of radio astronomers built a new “community” style of science opposing the “glamour” of nuclear physics. A Single Sky describes a communitarian style of science, a culture of interdisciplinary and international integration and cooperation, and counters the notion that recent science has been driven by competition. Collaboration, or what a prominent radio astronomer called “a blending of radio invention and astronomical insight,” produced a science as revolutionary as Galileo's first observations with a telescope. Working together, the community of radio astronomers revealed the structure of the galaxy.
