Abstract
The ESA INTEGRAL Space Observatory is approaching his 9 th year in orbit and has produced an unprecedented harvest of results in the soft gamma ray range, ranging from the inventory of the high energy sources, to the discovery of hundreds of variable soft gamma-ray sources to the mapping of the Al and annihilation line in the Galaxy. Recently, INTEGRAL observing strategy has supplemented the deep observations of the Galactic Centre and Plane with the deep observation of the extragalactic sky demonstrating soft (15 keV to 10 MeV) and high energy gamma FERMI and AGILE sky are barely overlapped. The IBIS Survey Catalogue 4 [Bird, A. J.; Bazzano, A.; Bassani, L., et al., APJS, 186, 1, 2010] contains more than 700 sources detected from 20 keV up to several hundreds of keV. In this short paper we will outline the latest view of the INTEGRAL high energy sky with particular regard to sources emitting at high energy, cosmic rays and gamma rays of Galactic origin.
