OSSE Map of the Galactic Center at 511 keV

OSSE Map of the Galactic Center at 511 keV

The colors in this map represent the intensity of gamma-ray emission from positron-electron annihilation in the plane of our Galaxy near the Galactic center. The emission is at 511 keV, which is the rest-mass energy of the electron and positron. The map is of a model that fits the OSSE 511 keV observations. OSSE has discovered that the radiation is mostly contained in a region of about 10 degrees diameter centered on the center of the Galaxy. The line plot superimposed on the map represents an OSSE observation of the 511 keV emission line.
