High-energy Gamma-ray Astronomy
Nature, 1970Gamma-ray astronomy above 10 MeV is difficult from the experimental point of view, but promising data are beginning to appear, as this survey progress report shows.

Abstract The observational status of gamma-ray astronomy in the TeV energy range is rapidly changing and is reviewed (1987) with emphasis on the limitations of the present observations. It is apparent that gamma-ray detection techniques must be improved and some methods by which this can be achieved are outlined.

Abstract Gamma-rays are located in the hard electromagnetic wave band. The range of measured energies is restricted to the interval between about 105 eV and 1016 eV (the latter is the highest energy of detected particles which are supposed to be gamma-ray photons). Gamma-ray astronomy is relatively young—approximately 25 years old.

Covering a broad energy range from ∼100 GeV to 100 TeV and above, celestial TeV gamma rays are accessed by telescopes based on the ground, unlike x-rays and lower energy gamma rays, which can only be detected using instruments in space. The natural advantage this gives such telescopes in terms of collection area is now being exploited by a generation ...

This paper summarizes recent results in X-ray and γ-ray astronomy including measurements of galactic and extragalactic sources from 0.1 keV to 20 GeV from space, measurements of γ-rays at energies above 70 GeV from the ground as well as theoretical models for the emission of γ-rays and X-rays in galactic and extragalactic sources.

A brief review is presented of the predicted intensities of gamma radiation from celestial objects. This is followed by a discussion of the use of a balloon-borne spark chamber to measure these intensities and to study the background gamma-ray intensity at 2.8 atmospheric pressure over Texas.

Recent observations have marked the transition of gamma ray astronomy from a discovery phase to an exploratory one. This has been the result of the development of a number of very sophisticated sensitive telescopes and the opportunity to place them on space platforms.

The study of celestial gamma -rays represents the opening of one of the last observational windows in high-energy astrophysics. Gamma rays provide a unique method for observing the energetic processes which exist within many of the most unusual celestial objects.

The domain of gamma-rays is very extended and several observational techniques are needed to cover the range from the MeV region to the TeV region. The low energy side (up to tens GeV) is the domain of space based observatories. The very low energy gamma rays, up to a few MeV, can be detected with scintillator systems.
