The Physical Processes and Observing Techniques of Radio Astronomy


Book Description

This is a textbook for undergraduate courses on radio astronomy. Written by an active professor and researcher in the field, it begins by explaining why conducting observations at radio frequencies is so important, then reviews essential physics concepts corresponding to a sophomore-level curriculum or higher. Next, the book introduces students to single dish telescopes and interferometers. The most commonly encountered emission mechanisms seen in radio astronomy are then explained, along with examples of astronomical sources broadly divided into the types of sources seen in galactic and extragalactic observations. Each chapter provides examples and exercises suitable for homework assignments. Also included is an appendix of useful supplementary material. Altogether, the book is a comprehensive, yet digestible starting point for physics and astronomy undergraduates looking to understand the basics of radio astronomy.

Fundamentals of Radio Astronomy


Book Description

As demonstrated by five Nobel Prizes in physics, radio astronomy has contributed greatly to our understanding of the Universe. Courses covering this subject are, therefore, very important in the education of the next generation of scientists who will continue to explore the Cosmos. This textbook, the second of two volumes, presents an extensive introduction to the astrophysical processes that are studied in radio astronomy. Suitable for undergraduate courses on radio astronomy, it discusses the physical phenomena that give rise to radio emissions, presenting examples of astronomical objects, and illustrating how the relevant physical parameters of astronomical sources can be obtained from radio observations. Unlike other radio astronomy textbooks, this book provides students with an understanding of the background and the underlying principles, with derivations available for most of the equations used in the textbook. Features: Presents a clear and concise discussion of the important astronomical concepts and physical processes that give rise to both radio continuum and radio spectral line emission Discusses radio emissions from a variety of astronomical sources and shows how the observed emissions can be used to derive the physical properties of these sources Includes numerous examples using actual data from the literature




Tools of Radio Astronomy


Book Description

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




Essential Radio Astronomy


Book Description

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







The Radio Sky and How to Observe It


Book Description

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.
