Galactic
* Galactic centre: discovery of new source with persistent hard X-ray emission coincident in position with the super-massive blackhole Sgr A*
* 511 keV all-sky survey of the electron-positron annihilation line
* Compact sources as the origin of the Galactic diffuse soft gamma-ray emission
* Discovery of new type of highly absorbed X-ray binary sources
* New insights into high energy part of the spectrum of magnetars
* Observations of line emission from the young supernova remnant Cas A to constrain the underlying physical model
* Detailed observations of accreting ms-pulsar IGR J00291+5934, considered to be the missing link between normal radio pulsars and isolated radio ms-pulsars
* Comparative observations of gamma-ray line emission from 26Al and 60Fe in the galactic centre and nearby star-forming Cygnus region

Extragalactic

* Active galactic nuclei: gathering of more evidence for a doughnut shaped gas cloud to be responsible for obscuring the accretion disk from our view
* Gamma-ray Bursts (GRB): observation of faint GRB suggests the existence of a hither-to unnoticed population of sub-energetic GRB
