INTEGRAL/IBIS Hard X-ray Galactic survey above 100 keV

INTEGRAL observatory has established itself as very successful mission in surveying hard X-ray sky at energies above 20 keV. The sky census at these energies mainly comprises well known accreting-powered compact objects. It is expected that at energies above 100 keV thermal emission processes should be gradually replaced by emission from non thermal particles. This transition region is still largely unexplored despite its potential importance. We present 10-year survey of the sky at energies above 100 keV which is based on substantial extension in exposure with respect to previous INTEGRAL hard X-ray surveys at these energies. We present catalog of detected sources, their statistics and spectral properties.
