The first part of this book gives a complete introduction to the instrumentation and techniques needed for radio-astronomical research. After a thorough survey of electromagnetic wave propagation, antenna theory and the design of receivers are dealt with. Radiation mechanisms relevant to radio astronomy are the subject of the second part of the book. Discussions of the 21cm line of hydrogen, the recombination lines, and the emission from interstellar molecules illuminate those tools of radio astronomy which allow the derivation of the physical parameters of interstellar medium.

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.

Covering topics of radio astronomy, this book contains graduate-level problems with carefully presented solutions. The problems are arranged following the content of the book "Tools of Radio Astronomy" by Rohlfs and Wilson (also available in this series) on a chapter-by-chapter basis. Some of these problems have been formulated to provide an extension to the material presented in "Tools of Radio Astronomy".

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.

Der neue Kosmos bietet in überschaubarem Umfang eine zusammenhängende Einführung in das Gesamtgebiet der Astronomie und Astrophysik. Der korrigierte und erweiterte Nachdruck trägt dem rasanten Fortschritt der astronomischen Forschung und Beobachtungsmöglichkeiten in den zwei Jahren seit dem ersten Erscheinen der 7. Auflage Rechnung. Die wichtigsten neuen Ergebnisse, vor allem bei unserem Planetensystem, bei der Neutrinostrahlung der Sonne, bei den fernsten Galaxien und Quasaren sowie bei der Entwicklung des Universums werden berücksichtigt.

In diesem kompetent geschriebenen Lehrbuch wird, ausgehend von der Beschreibung unserer Milchstraße, die Astronomie der Galaxien und ihrer großräumigen Verteilung eingehend dargestellt und schließlich im kosmologischen Kontext diskutiert. Aufbauend auf eine Einführung in die moderne beobachtende und theoretische Kosmologie wird die Entstehung von Strukturen und astronomischen Objekten im frühen Universum besprochen.

Der nach Stephen Hawking prominenteste Astrophysiker des Planeten hat das ultimative Kompendium über den Kosmos verfasst. In Neil deGrasse Tysons Bestseller ist alles versammelt, was wir über das Universum wissen: über Exoplaneten und Dunkle Energie, über Zwerggalaxien und den Urknall. Der Autor begeistert wie kein Zweiter mit funkelndem Witz für die Wunder des Weltalls. Zugleich regt er zum Nachdenken über unseren Platz im Universum an und zu Demut angesichts kosmischer Skalen. Sein „Universum für Eilige“ ist das perfekte Buch für alle, die auf nur 200 Seiten die heutige Astrophysik verstehen – und sich dabei auf hohem Niveau unterhalten lassen möchten.

Aus den Rezensionen zur 2. Auflage: "Experimente, Experimente, Experimente. Statt sich an der geschichtlichen Entwicklung von Welle-Teilchen-Dualismus, Schrödinger-Gleichung und anderen Meilensteinen der Quantenphysik zu orientieren, stellt Leisi die zu Grunde liegenden Experimente in den Mittelpunkt seines Buches. ... Um es mit den Worten Einsteins zu sagen: Das Buch ist im besten Sinne ‘grundlegend-naturhaft-einfach‘!" (www.buchkatalog.de)
