Abstract

Astronomy is now performed over the entire range of the electromagnetic spectrum, from radio to γ-ray energies. From the so-called “New Astronomies”, which are performed outside the optical window, we learned during the second half of the 20th century that each spectral range provides specific information which cannot be obtained by other means. Gamma radiation represents the most energetic part of the electromagnetic spectrum (see Fig. 1.1). Therefore it is natural that it provides information about the most energetic processes and phenomena in the Universe.
