In this chapter, after briefly reviewing the history and status of GRB science, we present some astrophysical results of the application of
the GRBM response functions and data analysis techniques, presented in chapters 3 and 4, to the flux and spectral study of high energy transients, mainly Gamma-Ray Bursts. Particular emphasis is given to the study of those events detected also by the WFC, for which a nearly unprecedented broad band (1.5-700 keV) spectral analysis is
possible. Many results of these analysis have been included in published papers, the more relevant of which are attached in Appendix A and are complementary to the content of this chapter.
The last section is dedicated to GRBM study of SGR1900+14, whose results are included in a paper (Feroci et al., 1999) accepted for publication on
Astrophys. J.and have a relevant astrophysical value.
