Uspekhi Fizicheskih Nauk, 1974
A review is presented of the observational data on detection of cosmic γ rays. The importance of observations in γ astronomy in solution of a number of basic problems of cosmic-ray physics, astrophysics, and cosmology (for example, the origin and sources of cosmic rays) is emphasized.

Theoretical astronomy and observation
Physics Bulletin, 1972Theoretical astronomy is in a phase of seeking to explain recent observations by existing theory – thereby testing the theory – rather than constructing much new general theory. The failure of the latest attempts to detect neutrinos from the sun poses serious problems.

Astronomy is fundamentally an observational science and as such it is important for astronomers and astrophysicists to understand how their data are collected and analyzed. This book is a comprehensive review of current observational techniques and instruments. Featuring instruments such as Spitzer, Herschel, Fermi, ALMA, Super-Kamiokande, SNO, IceCube,

Observational Molecular Astronomy
2013Molecular line emissions offer researchers exciting opportunities to learn about the evolutionary state of the Milky Way and distant galaxies. This text provides a detailed introduction to molecular astrophysics and an array of useful techniques for observing astronomical phenomena at millimetre and submillimetre wavelengths.

Babylonian observational astronomy
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1974Abstract The cuneiform texts from ancient Assyria and Babylonia that are preserved offer direct evidence for systematic astronomical observation in two widely separated periods. From the first half of the second millennium B.C., later tradition has transmitted the dates of successive Venus appearances and disappearances in the reign ...

Observation of Scientific Publications in Astronomy/Astrophysics
2000L'une des missions de l'Observatoire des sciences et techniques (OST) est de contribuer aux débats de politique scientifique par la production d'indicateurs sur la science et la technologie. Dans ce travail, les indicateurs sur les publications scientifiques en astronomie/astrophysique ont été élaborés à partir des données de l'Institute for Scientific

Autonomous observation scheduling in astronomy
Observatory Operations: Strategies, Processes, and Systems VII, 2018Rapid technology development has opened up exciting new possibilities in astronomy with larger, more sensitive telescopes that cover large frequency ranges. Telescopes have become bigger and more complex, housing multiple instruments and having wide ranging science aims.

Publisher Summary In order to present the over-all pattern of radio astronomy this chapter discusses the main results concerning the Sun, the Milky Way, and external galaxies. It deals with the observational methods used to study the universe at radio frequencies. The application of these methods is illustrated.

Simultaneous observation techniques in astronomy
Endeavour, 1985Abstract Modern optics and electronics have now reached the stage where various techniques can be adopted to carry out combined and simultaneous astronomical observations of the same objects in order to understand their nature. This requires not only an administrative but also a technical coordination, e.g.
