The first event was recorded in 1967 but the existence of gamma-ray flashes coming from the cosmos was not announced to the scientific community until 1973 (.; Figure 1.1). GRBs are brief and bright, lasting from

In the introduction to this chapter, it is important to mention the remarkable work done by the scientific and technical teams, which were strongly motivated by two researchers, E. Costa and F. Frontera. These two reseachers were very excited by the GRB mystery

Rechnen mit beliebigen Zahlen und Einheiten, the main properties of gamma-ray bursts with standard physics applied to somewhat ‘exotic’ objects. In this chapter we outline the most popular model to explain GRBs and their afterglows. This model, with its basic ingredients, has very often been called the standard model.

As most GRBs are probably collimated with typical opening angles between 1° and 20°, the true energy is clustered around 10. to 10. ergs which must be liberated i
