Scientific paper

Nine years of observations with the CGRO/OSSE instrument have allowed the first maps of positron annihilation radiation. The extraction of annihilation radiation from a complex spectrum composed of both compact and diffuse sources depends upon the unique spectral signatures of 511 keV line and positronium continuum emissions. We report here results of a re-analysis of OSSE obtained spectra of the galactic center region. We show updated maps of annihilation radiation, and discuss how these maps influence the interpretation of suggested sources of galactic positrons.
