Download or read book Essential Radio Astronomy written by James J. Condon and published by Princeton University Press. This book was released on 2016-04-05 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ideal text for a one-semester course in radio astronomy Essential Radio Astronomy is the only textbook on the subject specifically designed for a one-semester introductory course for advanced undergraduates or graduate students in astronomy and astrophysics. It starts from first principles in order to fill gaps in students' backgrounds, make teaching easier for professors who are not expert radio astronomers, and provide a useful reference to the essential equations used by practitioners. This unique textbook reflects the fact that students of multiwavelength astronomy typically can afford to spend only one semester studying the observational techniques particular to each wavelength band. Essential Radio Astronomy presents only the most crucial concepts—succinctly and accessibly. It covers the general principles behind radio telescopes, receivers, and digital backends without getting bogged down in engineering details. Emphasizing the physical processes in radio sources, the book's approach is shaped by the view that radio astrophysics owes more to thermodynamics than electromagnetism. Proven in the classroom and generously illustrated throughout, Essential Radio Astronomy is an invaluable resource for students and researchers alike. The only textbook specifically designed for a one-semester course in radio astronomy Starts from first principles Makes teaching easier for astronomy professors who are not expert radio astronomers Emphasizes the physical processes in radio sources Covers the principles behind radio telescopes and receivers Provides the essential equations and fundamental constants used by practitioners Supplementary website includes lecture notes, problem sets, exams, and links to interactive demonstrations An online illustration package is available to professors

This book was released on 2015-11-02 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electromagnetic spectrum is a vital part of our environment. Measures of radio frequency emissions from natural phenomena enable both practical applications, such as weather predictions and studies of the changing of Earth's climate here at home, and reveal the physical properties of cosmic sources. The spectrum is therefore a resource to be used wisely now and to be protected for future generations. Handbook of Frequency Allocations and Spectrum Protection for Scientific Uses: Second Edition sets forth the principles for the allocation and protection of spectral bands for services using the radio spectrum for scientific research. This report describes the radio frequency bands used by scientific services and includes relevant regulatory information and discussion of scientific use of frequency bands. This reference will guide spectrum managers and spectrum regulatory bodies on science issues and serve as a resource to scientists and other spectrum users.
Book Synopsis The Low-frequency Radio Universe by : Homi Jehangir Bhabha
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.
Book Synopsis Tools of Radio Astronomy by : K. Rohlfs
Download or read book Tools of Radio Astronomy written by K. Rohlfs and published by . This book was released on 2004 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This substantially rewritten and expanded fourth edition outlines the most up-to-date methods and tools of radio astronomy. Tools of Radio Astronomy gives a unified treatment of the entire field of radio astronomy, from centimeter to sub-millimeter wavelengths and using single telescopes as well as interferometers. The basic physical principles are described and a complete outline of the instrumentation, observational techniques, and methods of measurement and analysis are given. The goal of this standard reference and text is to prepare readers to carry out observations and relate the data to physical processes in interstellar space. In this fourth edition, the chapter on interferometry and aperture synthesis has been thoroughly revised in the light of most recent developments, as has been the chapter on molecules in interstellar space, and material on receiver technology. From reviews of previous editions: "People use this book so much because it describes what one needs in order actually to do radio astronomy ... and it will remain relevant for a long time...This book is an excellent graduate level text - the best available by far. It is also the best reference book for the practising astronomer who wants to do radio astronomy properly, to interpret the jargon or to understand some of the details of current literature." Physics Today "This is the one book you should buy if you want to become a radio astronomer. (...) I have used the first and second editions as a postgraduate textbook for many years, and will now recommend the third edition to my students." The Observatory.

Book Synopsis Low Frequency Radio Observations of Galaxy Clusters and Groups by : Thérèse Cantwell
Download or read book Low Frequency Radio Observations of Galaxy Clusters and Groups written by Thérèse Cantwell and published by Springer. This book was released on 2018-09-01 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book uses new data from the very low radio frequency telescope LOFAR to analyse the magnetic structure in the giant radio galaxy NGC6251. This analysis reveals that the magnetic field strength in the locality of this giant radio galaxy is an order of magnitude lower than in other comparable systems. Due to the observational limitations associated with capturing such huge astrophysical structures, giant radio galaxies are historically a poorly sampled population of objects; however, their preferential placement in the more rarefied regions of the cosmic web makes them a uniquely important probe of large-scale structures. In particular, the polarisation of the radio emissions from giant radio galaxies is one of the few tools available to us that can be used to measure magnetic fields in regions where the strength of those fields is a key differentiator for competing models of the origin of cosmic magnetism. Low frequency polarisation data are crucial for detailed analyses of magnetic structure, but they are also the most challenging type of observational data to work with. This book presents a beautifully coupled description of the technical and scientific analysis required to extract valuable information from such data and, as the new generation of low frequency radio telescopes reveals the larger population of giant radio galaxies, it offers a significant resource for future analyses.
Book Synopsis Merging Processes in Galaxy Clusters by : L. Feretti
Download or read book Merging Processes in Galaxy Clusters written by L. Feretti and published by Springer Science & Business Media. This book was released on 2006-04-18 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mergers are the mechanisms by which galaxy clusters are assembled through the hierarchical growth of smaller clusters and groups. Major cluster mergers are the most energetic events in the Universe since the Big Bang. Many of the observed properties of clusters depend on the physics of the merging process. These include substructure, shock, intra cluster plasma temperature and entropy structure, mixing of heavy elements within the intra cluster medium, acceleration of high-energy particles, formation of radio halos and the effects on the galaxy radio emission. This book reviews our current understanding of cluster merging from an observational and theoretical perspective, and is appropriate for both graduate students and researchers in the field.

Book Synopsis New Eyes on the Universe by : Stephen Webb
Download or read book New Eyes on the Universe written by Stephen Webb and published by Springer Science & Business Media. This book was released on 2012-05-19 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: “New Eyes on the Universe – Twelve Cosmic Mysteries and the Tools We Need to Solve Them” gives an up-to-date broad overview of some of the key issues in modern astronomy and cosmology. It describes the vast amount of observational data that the new generation of observatories and telescopes are currently producing, and how that data might solve some of the outstanding puzzles inherent in our emerging world view. Included are questions such as: What is causing the Universe to blow itself apart? What could be powering the luminous gamma-ray bursters? Where is all the matter in the Universe? Do other Earths exist? Is there intelligent life out there? The renowned author explains clearly, without recourse to mathematics, why each question is puzzling and worthy of research. Included in the study of the wide range of sensitive and powerful instruments used by scientists to try and solve these problems are ones which capture electromagnetic radiation and ‘telescopes’ for cosmic rays, neutrinos, gravitational waves, and dark matter. This book discusses twelve areas of active astronomical research, ranging from the nature of dark energy to the existence or otherwise of extraterrestrial civilizations, and devotes one chapter to each topic. Although astronomers tackle each of these questions using information gleaned from all possible wavelengths and sources (and this is emphasized throughout the book), in this work the author dedicates each chapter to a particular observational method. One chapter covers X-ray telescopes for investigating black holes, while another uses infrared telescopes to learn more about planetary information.
Book Synopsis The Vanishing Universe by : Derek McNally
Download or read book The Vanishing Universe written by Derek McNally and published by Cambridge University Press. This book was released on 1994-09 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ironically, the technology that has made possible so many exciting astronomical discoveries is now jeopardizing the future of observational astronomy. The effects of atmospheric degradation, electromagnetic pollution, and near-Earth space debris are taking their toll. This provocative survey convincingly demonstrates the destructive impact of civilization on current observational astronomy. International astronomers discuss the sources and effects of environmental pollution and degradation and together with specialists from industry, law and elsewhere, they outline possible remedies and the legislation required for successful international regulation of the pollutants. These articles provide essential reference for the professional astronomer, environmentalist, and concerned nonspecialist.

Download or read book Wireless Radio written by Lewis Coe and published by McFarland. This book was released on 2006-02-22 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1873 Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.
