Detection of gamma-rays from the Galaxy in the spectral range of positron annihilation signatures. The significance of detecting a signal from the sky, summed over all spatial components as described in the text, is given for each 0.5 keV wide bin in units of σ. We can identify the intense line at 511 keV, together with an ortho-positronium continuum from positron annihilation, and an underlying gamma-ray continuum emission component.
