Limits for an inverse bremsstrahlung origin of the diffuse Galactic soft gamma-ray emission
Martin Pohl
RXTE, GINGA, and OSSE observations have revealed an intense low-energy gamma-ray continuum emission from the Galactic plane, which is commonly interpreted as evidence for the possi…

An annihilation fountain at the Galactic center?
Martin Pohl
Recently, data of taken with the OSSE experiment have been combined with scanning observations by TGRS and SMM to produce maps of the narrow Galactic 511 keV line emission (Purcell…

Diffuse gamma-ray emission: Galactic and extragalactic
Martin Pohl
Here is reviewed our current understanding of Galactic and extragalactic diffuse gamma-ray emission. The spectrum of the extragalactic gamma-ray background above 30 MeV can be well…
