Available in PDF, EPUB and Kindle. Book excerpt: Radio astronomy is an active and rapidly expanding field due to advances in computing techniques, with several important new instruments on the horizon. This text provides a thorough introduction to radio astronomy and its contribution to our understanding of the universe, bridging the gap between basic introductions and research-level treatments. It begins by covering the fundamentals physics of radio techniques, before moving on to single-dish telescopes and aperture synthesis arrays. Fully updated and extensively rewritten, the fourth edition places greater emphasis on techniques, with detailed discussion of interferometry in particular, and comprehensive coverage of digital techniques in the appendices. The science sections are fully revised, with new author Peter N. Wilkinson bringing added expertise to the sections on pulsars, quasars and active galaxies. Spanning the entirety of radio astronomy, this is an engaging introduction for students and researchers approaching radio astronomy for the first time.
Download or read book The Invisible Universe written by Gerrit Verschuur and published by Springer. This book was released on 2015-01-23 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hidden from human view, accessible only to sensitive receivers attached to huge radio telescopes, the invisible universe beyond our senses continues to fascinate and intrigue our imaginations. 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. 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. The author discusses what radio astronomers are doing in the New Mexico desert, in a remote valley in Puerto Rico, and 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, or perhaps who, is out there as well. The author specifically highlights enormous changes that have occurred in the field over the past 50 years, including the political reality of radio astronomy and what that could mean for the future.

Download or read book Golden Years of Australian Radio Astronomy written by Wayne Orchiston and published by Springer Nature. This book was released on 2022-01-20 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of Australian radio astronomy from 1945 to 1960 has been studied in detail by numerous historians of science in recent years. This Open Access book is the first to present an overview of this remarkable chapter in Australian science. The book begins in the post-war period, as the Radiophysics Laboratory in Sydney switched from secret wartime research on radar to peacetime applications of this new technology. Next follows the detection of radio waves from space and the ensuing transformation of this fledgling science into the dominant research program at the Radiophysics Lab. Drawing from this history, the book shows how by 1960 the Radiophysics Lab had become the largest and most successful radio astronomy group in the world. The final chapter presents an overview of Australian radio astronomy from 1960 to the present day, as Australia prepares to co-host the multi-national, multi-billion-dollar Square Kilometre Array. Nearly 300 high-quality images complement the text, drawn from a wide range of sources including the extensive collection held by the CSIRO Radio Astronomy Image Archive. The book will be an essential reference for readers interested in the scientific and cultural development of radio astronomy. This book is published open access under a CC BY 4.0 license.
Download or read book A Single Sky written by David P.D. Munns and published by MIT Press. This book was released on 2012-10-26 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Low frequency Radio Universe written by Homi Jehangir Bhabha and published by . This book was released on 2009 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: A strong resurgence of interest in low-frequency radio astronomy in the past few decades has led to addressing many of the outstanding and challenging astrophysical and technical problems and issues. The GMRT has been in operation for close to a decade. Early results have been reported from LOFAR. The next generation of telescopes such as the LWA, MWA, MeerKAT, ASKAP and SKA should provide exciting challenges, results, and opportunities. To discuss recent results and astrophysical problems as well as a range of technical issues at low radio frequencies, a conference and workshop was held at the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research. This event commemorated the birth centenary of Dr. Homi J. Bhabha, who contributed immensely in both the sciences and the arts. There were approximately 130 participants from over a dozen countries. The conference brought together experts with a wide range of interests from major observatories and institutions across the world as well as younger research workers largely from within India. There were over 100 papers presented, including several extensive reviews, on a large variety of topics including low-frequency surveys and cosmology, extragalactic neutral hydrogen and OH, extragalactic radio sources, clusters of galaxies, our Galaxy, pulsars, transients and high-energy sources, Sun and planetary studies, and instrumentation and techniques. The book provides an overview of research at low radio frequencies and should be of interest to a wide spectrum of students and researchers.
