10 GRBs and a subclass of Type Ic SNe (hypernovae: very broad spectral lines ) SN 1998bw - GRB 980425 SN 2003dh - GRB 030329

11 GRBs from stellar explosions…

12 The mystery of the unidentified gamma-ray sources

13 Excellent gamma-ray imaging with a large Field-of-View (2.5 sr) Simultaneous broad-band spectral information (15-40 keV, 30 MeV – 30 GeV) Microsecond timing Efficient transient detection and alerts AGILE: Italian Small Mission
