George Koelsche Sun, the calculation of the expected γ-ray fluxes from the different production mechanisms is on a reasonably firm basis since experimental results are available (cf. Sections V-5.1 and V-5.2). In addition, the evidence for a γ-ray line feature near 500 keV from the direction of the Galactic Cente

George Koelschto monitor possible nuclear explosions within and outside the atmosphere of the Earth. 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

George Koelschand the ProportionalCoun ter Array (PCA) instruments have detected 30 GRBs. In 16 cases, an early celestial position was released to the community, sometimes in conjunction with IPN results. The subsequent optical and radio searches led to the detection of 5 x-ray afterglows, to at least 6 optical o
