Die Funktechnik ermöglicht die Ausweitung der astronomischen Beobachtungen über das Licht hinaus auf andere Frequenzbereiche. Dies führte zur Entdeckung zahlreicher kosmischer Radioquellen, deren physikalische Ursachen erläutert werden, ebenso die Funktionsweise eines Radioteleskops. Schon mit kleinen Radioteleskopen kann die Strahlung der Sonne und anderer Radioquellen sowie die 21-cm-Strahlung aus der Milchstraße beobachtet werden. Durch Interferometrie kann eine wesentlich höhere Auflösung als mit einzelnen Radioteleskopen erzielt werden. Dadurch kann die radioastronomische Forschung zu vielen aktuellen Fragen der Astronomie, Kosmologie und Physik beitragen.
Radio technology enables the extension of astronomical observations beyond light to other frequency ranges. This has led to the discovery of numerous cosmic radio sources, the physical causes of which are explained as well as how a radio telescope works. Even small radio telescopes can observe radiation from the Sun and other radio sources, as well as the 21-cm radiation from the Milky Way. Through interferometry, much higher resolution can be achieved than with individual radio telescopes. As a result, radio astronomical research can contribute to many current questions in astronomy, cosmology, and physics.
This Springer essential is a translation of the original German 1st edition essentials, Radioastronomie by Thomas Lauterbach, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
